Not to end

Design description:
The pencil can not be made full use of ,a quarter in the end is left over.
So we should shorten the length of ink,avoid reaching the end of the pencil.
As a result, when it is too short to use ,the ink has used up too.
Finally,only wood left ,which can recycle directly ,withjout any waste.
