Box for fixpencil

I create this box to hold in a safe place two pentel fixpencils.
My students use very bad container for the pencils and pens, this easy bent the tip of the fixpencil, and they become unusable.
With this printed container, which hold two pieces of them (0.3 and 0.5mm) and they are now protected again chocs. Hopefully, they wont need to buy new one's!
