Thanks for checking out the Pocket Scroll Keychain!
The Pocket Scroll is only 6 cm long but packs enough power for a detailed diary, ultimate shopping list, or ninjutsu summoning. It won't unroll on it's own and it's easy to remove a section to give away! With basic printer paper it holds 4cm x 80cm and I bet you could get double with thin receipt paper.
Follow the images for easy assembly and a special treat. Insert paper in the slot and twist it up, it's that easy.
I included some specialized print files with custom supports along with all models, enjoy!
