optimal design paper tube / toilet paper

optimal design paper tube
optimal design paper tube

It always take much of our time to take the paper tube out of the roll paper ,sometimes may impair our fingernail.
The idea of this work is based on the original one and we add two sawtooth mark inside of the paper tube.This small change,which reflect humanization of this work.
You can take the paper tube easily when you tear a little piece of paper along the sawtooth mark ,which it is very convenient.
