LEAF / Pencil

LEAF

Sometimes,we find we have a lot of pencil but it's hard to find a ruler.You might have use a pencil as ruler but it didn't have graduation.I use leaf instead of number ,the distance between two leaves is one centimeter.
The leaf represents the tree ,to appeal people to cherish the resources.Besides,we also know more clearly the percentage of
pencil that can be used.
