I had been investigating the Moonman/Majohn C1 & the C4 for some time, and happened to have your review come up. Loved the review Chris. Between the 2 pens I prefer a Japanese style eyedropper, and thus had ordered a C4 which should arrive in the next couple of days. Thanks to this review I have a better understanding of the size of the pen I ordered. Best Regards.
The models I have are the C1,C3,S5 and Q1. I’m glad to see the C4 comes with English instructions and a medium nib. My favourites were the C1,C3, S5. The Q1 was nifty but I haven’t used it in a while .
That shutoff valve is essential. All eye dropper pens should use a mechanism to prevent burping. Thanks for a great review. I like the looks of the clear C4. 👍👍👍(wow 3 thumbs up - my highest rating possible 😎).
Thank you. For me, shut-off valve not required. I've carried around many ED pens & have not had issues. I've had more C/C pens burp. The valve adds complexity & a failure point. I like a simple ED filler.
That's an appealing pen. Though I never understand when the aesthetic choice is made to mix steel and gold colors. Choose one, make all the metal visible in the pen that color.
Especially in a clear demonstrator pen that mixing of trim colors bothers me. I might have to wait for Gen 2 which for me would mean more color options and matching trim. This could become a serious competitor for Opus 88, especially since the Majohn retails for a quarter of the Taiwanese pens.
Looks like what I have been looking for, some pen to replace a clear OPUS 88 that I dropped and broke! I love the shut-off valve-equipped eyedropper. Thanks for the review, since I was unaware of this model. As always, great job! KW
@@Seefood73 Both are overrated anyways, the real heat are those IPG nibs. 😎 On a serious note, since this Moonjuice pen uses a #6 nib, you can just pull out that sucker and pop in either a #6 Jowo or Bock nib, not every pen needs threads to be Jowo or Bock compatible :/
@@i.c.3157 I swap #5 and #6 nibs a lot, but not all are made equal and not all nibs fit all collar+feed combos because of length and thickness. Jinhao seems to be very accommodating to others, PenBBS not so much, the tolerance for thicker nibs is very low, and not all caps are deep enough for long nibs such as the Noodler's Ahab nib. Also many users are not keen on pulling apart nib assemblies like you and I... The one big plus of a #6 Jowo-threaded section is that most of them will also take a Pilot Parallel Pen nib unit without modifications, like Opus88 Omar or demo, or models of Franklin Christoff, and artists love that.
Doug made the point that they are probably keeping Moonman on the actual pen design. All package and web branding can be Majohn so the product can be sold in Europe etc
Thanks for the review, Chris. It’s very useful. Like other commenters I see the similarity to the Opus 88, but think it is less a copy and more an inspiration. I will probably order one, since I’m very fond of demonstrators. After thinking it twice, it seems more like the Conklin All American demonstrator but as an eye dropper.
As you may figure out, I find the fixation on any Chinese pen must be a copy very inaccurate. But these same people don't look at other pens that copy other designs the same. This is a very old filling system. Opus 88 uses it more than most but is certainly not the originator of the design. I focus on the pen in my hand & show that to you.
@@chrisrap52 I would think since this filling system is called Japanese eyedropper, the origins are in... Japan. I'd love to see your reviews of (vintage) Japanese pens with this filling system.
As in all Chinese creations, nothing is random and everything has its own meaning. My theory for the two colors of the parts of the fountain pen. The internal parts like the silver-colored nib, like the moon. The external parts, like the gold-colored clasp, like the sun. Between night and day, clouds of ink immersed in the exceptional transparency of the sky. Thanks Chris for your other professional and helpful review!
Thanks for posting. It looks like it's trying to copy a page from the Opus 88 playbook. The only thing that's a bit weird is that the nib and piston are silver, and the cap clip and ring gold. An all silver look looks more uniform, and would fit it better.
Just watching this again because I'm thinking about buying one. You do great reviews, Chris. I always enjoy them. Question: Which do you prefer, this or the C1? Are you still enjoying this one?
Yes, I use the C4 more than C1. Both hold a lot of ink. I like the C4 slightly more. Bigger, like the look. The C1 is also a good writer but the C4 is a little better in many ways. I forget to open blind cap on C4 is the only downside.
So they've come for the Opus 88. I might, meaning yes I will, get one to see how it feels in hand compared to the Opus, something about their sections just feel nice.
@@chrisrap52 My apologies, it was meant as a more of a joking statement. I used to have one of the older Japanese pens with the valve shut off and until Opus 88 emerged the only people who made them like this was Danitrio and their cheapest model is like 500% more expensive. I'm actually surprised that Majohn beat PenBBS to this.
Which seller did you get this pen. I would like to get all the packaging too. Beautiful pen. I just got the C1. If I had waited I would have certainly gotten this pen. As for eyedropper pens MaJohn seems to have embraced the version. PenBBS makes the 323 that works very well but it is their only model. Jinhao and Hong Dian do not make such a pen, I think.
Btw - C1 can be cartridge/converter as well - I have 2 of them and both came with converters. I was pleasantly surprised to see Moonman doing a bulk filler pen. I believe this is currently the cheaper bulk filler. Mine is still on the way... 😑
I guess my mother forgot to invite the Malevolent Fairy to my christening, so I was cursed with every fountain pen randomly burping at my touch. Obviously you Chris, was on the contrary blessed from ever experiencing that. Did your mother immerse you, as a baby, in a cauldron of magic ink, holding you by your heel?😄
I've been using fountain pens for almost 60 years. Have learned a bit. As an engineer I focus on understanding how things work. And I am generally lucky. A tray of broken pens were the unlucky ones, but I learned from each one.
I knew @chrisrap52 would do me a solid and tell me what the ink capacity of this thing is when everybody else just describes it as "holds a lot of ink". Thank you! I'll wait for them to make something that can hold 6ml of ink.
I have not had any burping. Any pen can burp, ED's a little more. Just need to practice proper care, Nib up until writing. Avoid large temperature changes. If you like the pen, want a large ink supply, give it a try. With shut off valve burping is avoided when not writing.
Great vid! I would have never found this pen on my own. Any chance you have a section diameter on it? I love thicker sections! Thanks again for a great vid.
Hi Thanks for the great video Do you know if you can screw in a bock 250 (number 6) nib unit (threading in the whole unit not just the nib) Into this pen?
Thanks a lot..I wanted to order a housing from fnf for my beloved pilot fa nib n10 but sadly they only have adapter for bock or Jowo If you have any idea how can I use this nib in this pen it will be great

I avoid the events that can lead to burping. Keep pen full. Never uncap nib down. Store pen nib up. If pen cold, allow it to reach room temp before writing. Burps are usually caused by air inside pen pushing ink out.
@@chrisrap52 I guess my curse is that I want to use as much of the pens capacity as possible, before refilling, and also impatiently moving around with a pen in my pcket between different temperatures. Maybe the C4 is the pen for me!?
10:55 this is Wancai 丸彩 1， in acrylic. But new color in 2023. All Wancai 2 are molding, half price of Wancai 1. Majohn is confusing, plus the irresponsible oversea sells having no clue what they are selling.
I like how they kept the rod from interrupting the lens effect of the end knob. Nice aesthetic.

@@chrisrap52 good point!
Purchased the C4 based on this review with the devious intention of swapping in the Q1 Fude nib. Worked well but with an obvious learning curve.
My medium is a great writer. My C4 has been inkde in use since my review.
Among all Majohn eyedroppers, only c4 reminds me the most with my grandpa's Waterman in early 1930s.
Good pen, mine continues to do well.
Great video and a really cool looking pen. Definitely adding this to my list.
It fits a pilot parallel nib, could be great for demonstrating inks!
Thanks again Chris for a very informative and detailed review.
Keep up the great work and be well.
Thanks, will do!
Can’t wait for mine to come in-love that clear acrylic! Thanks!
Hope you enjoy it!
C2 stays inked on my desk all the time. Enjoy it so much.
That's an appealing pen. Though I never understand when the aesthetic choice is made to mix steel and gold colors. Choose one, make all the metal visible in the pen that color.

The only downside is the threading is not Jowo or Bock as in the Opus88 pens.

Thank you! You too!

My C4 and my Asvine P30 both arrived today. I got medium nibs so i can shape them! So excited!
Great, have fun with them.

I've a C1, but it came with a converter... and an eyedropper, so I've options with that one. Definitely want to try the C4 with a medium nib.
Yes, I forgot that.
They'll always be Moonman to me.
I will always call my future Majohn pen as Moonman so it's okay Chris.
⭐🤠Like the acrylic and the shape. Something different in the pens 🌎 ✍️✍️✍️✍️✍️✍️💚
Thank you again For all the review s. As always ⭐⭐⭐⭐⭐⭐⭐⭐
I like demonstrators, but the wimpy pocket clip on this one is a deal breaker for me. Well done review!
Not wimpy, it's petit. Think Sheaffer Tuckaway.
Thanks for posting. It looks like it's trying to copy a page from the Opus 88 playbook.
The only thing that's a bit weird is that the nib and piston are silver, and the cap clip and ring gold. An all silver look looks more uniform, and would fit it better.
That color mismatch is strange.
I agree on the colors of the metal. I just find that gold and steel clash, so just pick one, please.
Chris, is it possible to disassemble the clip and use it without the clip? Great video. Thanks for all your time and effort.
Possible yes, remove the screw that holds clip.

No one is coming after anyone. As I mention this is an old filling system, many pen makers use. The section is nice.

I expect PenBBS will eventually have a similar filling system. They seem to enjoy using different methods to fill a pen.
Sorry another question. I'm new to this brand... Do they fit jowo or bock nib units (or at least jowo/bock nibs) if someone wanted to swap?
Yes, uses No. 6 size.

Will you be doing a review of the S7? Does it have a shut off valve? Does it carry a #6 nib?
No shut off valve. Review eventually.
Btw - C1 can be cartridge/converter as well - I have 2 of them and both came with converters.
I was pleasantly surprised to see Moonman doing a bulk filler pen. I believe this is currently the cheaper bulk filler.
Mine is still on the way... 😑
You are correct. I just never used the converter. Holds about 5ml of ink when ED.
Came here to say that :)
Thanks Chris, great video as always. The ink looks good but not much evidence of the glitter when applied to the page. Was that just the camera view?
Not heavy glitter. Angle is small to see. You can see a bit when I'm writing.
@@chrisrap52 thanks Chris

Are there burping problems? Considering this pen, but cant find info how it is for longer drawing and writing. Tnx.

@@chrisrap52 Thanks for info. Considering to buy soon bigger pen and this is my favorite so far.
Does the glitter/shimmer material in the ink clog the feed or nib?
No. I've used many. Had in pens for months/years. Yes it requires a little more cleaning but I love the glitter.
Great vid! I would have never found this pen on my own. Any chance you have a section diameter on it? I love thicker sections! Thanks again for a great vid.

Hi
Thanks for the great video
Do you know if you can screw in a bock 250 (number 6) nib unit (threading in the whole unit not just the nib)
Into this pen?
Cannot screw in a Bock. Can swap nib.
Thanks a lot..I wanted to order a housing from fnf for my beloved pilot fa nib n10 but sadly they only have adapter for bock or Jowo
If you have any idea how can I use this nib in this pen it will be great
@@user-wj9ri2vy7k I haven't swapped Pilot nibs. Not sure a No. 10 would fit in the C4. You'll be the first.
@@chrisrap52 thank you
will let you know
The nib was #6, is your feed mark #2 on it ? Thanks
Nib #6, mark on feed not relevant.
I do wish they put the model number on the pen, especially as they laser engraved the band, so should have been easy enough.
👍
Is the nib unit the same as the Moonman P136?
All moonman/majohn #6 units are the same in my experience, thus interchangeable.
I was wondering that too. If I get one of these I wanted to have some spare nib collars for different nibs and a backup in case one breaks.
Enjoyed this. Which do you prefer the C1 or C4? Thanks
C4, larger, shut off valve, like the look.
@@chrisrap52 thanks. I did not realize, I think this company is now called Asvine?
They may be related but both exist.

Yes, they are resellers and may not accurately describe pen.
Aren’t mahjohn and Moonman the same brand? They show up if I search for Moonman pens so I feel you deserve a pass. 😊
Thanks. The name has officially changed to Majohn. But pens are sold under both names. Thanks for the support.
Not sure how functional that short clip is. Also it seems a bit disproportional to the length of the pen. Al least it can serve as a roll stop.
And it works as a clip.
I have Parkers Pens.
So do I.
I don't doubt it for a second.
