In-Out Eraser / Eraser

In-Out Eraser
In-Out Eraser

Using an eraser for a while has a problem that its length is not enough. The short length is not easy to use. Therefore, we design a connecting structure that one side is IN and the other side is OUT. The structure makes it could be assembled like building blocks. Then it will be an effective way to use the wasting part of an eraser.
