Telephone Mirror Box & Tardis Harbin Box by Made to Measure Magic

It looks just like the sort of thing you would find in any child's bedroom. It is a money box but has been converted to a mirror tube. Use it to produce, vanish of exchange any item that will fit into it.
It looks empty - take off the top and put in a red, white and blue silk hanky. Put the top back on and say the magic words. Remove the top and remove a Union Jack silk. The box now looks completely empty.

This fantastic looking Tardis is, in fact, a Harbin box so you can use it to produce, vanish or exchange one item for another.
