An innovative take on the classic disposable pen. By utilising a spiralled chamber twice the amount of ink can be stored. This means that fewer pens are needed and therefore less plastic is used in manufacture. A simple, yet effective sustainable solution!

Designed by Han Chi-hoon, Kim Yeon-soo, Park Byong-gon & Kim Sung-geun as part of the iF Concept Competition. 

This is a great solution for those who use pens regularly. Whilst I like to sketch in Biro during concept stages, I have never actually ran out of ink. This is mostly since I tend to either break or lose my pens before that can happen!
