Iroshizuku Tsuyu-kusa and Fountain Pens

In this video I take a looked at Iroshizuku Tsuyu-kusa in a variety of pens and nib sizes.
Note This ink has been discontinued but I think the standard Pilot blue ink would be a suitable substitute. I'll test Pilot Blue in the next review to make sure.

Thank you - you are so very thorough!!! ✨

[@gadgetstop321]

You're welcome! This is my version of playing around and relaxing with my pens and ink. 😀

A nice blue ink! ❤️ Is Kon-Peki a more turquoise or green ink in comparison? 😇🩷🙏🙌

[@gadgetstop321]

Kon-peki is more turquoise than Tsuyu-kusa. 😀

the first ink I bought was Diamine china blue which is quite a light, unsaturated ink but I seem to prefer much more saturated blues like Diamine oxford and midnight blue; don’t use tsuyu kusa in your vintage Esterbrook fp’s: Iroshizuku inks are slightly alkaline and will eat thro’ the latex sac!; thanks for this:)

You're welcome, Angus! I like Oxford Blue, too. Thanks for the heads up about Iroshizuku inks. I had heard that before, so I reserve my little collection of Iroshizuku inks for my modern pens, usually the dryer writing ones. When I started getting into lever filling pens, I bought a bottle of Waterman Mysterious Blue. It's the only ink I use in my vintage pens. 😀

@@gadgetstop321 mysterious blue is wonderful as is serenity blue(tbh, haven’t come across a Waterman ink I didn’t like except turquoise: not a fan of that at all:)
