MONO消しゴム
MONO is a brand of products created by the company Tombow Pencil.

The MONO product featured most in anime and manga is a plastic eraser that comes in a case with blue, white, and black bars. 

In many posts, what you'll see is a [[brand name imitation]]. For example, the case might say "NONO" and the bars might be colored differently.
