Eraser
Rubber
noun
You've seen the word 消す, I hope. This comes from that. You're extinguishing something with ゴム. ゴム is a word for either gummy or rubbery things. So, this is a gummy thing that extinguishes something. This is an eraser that extinguishes pencil markings.

けしゴム
The reading comes from 消す, so make sure you know that word so you can read this one!
