Erasers don’t get any funner than this. You probably don’t need an eraser at this point in time, but you might still want to get them anyway because they’re more than just erasers. You can think of them as attachments that turn plain old pencils into (partial) rods that you can use to play an impromptu foosball match.
It’s nothing like the real thing, obviously, but it provides some fun where there used to be none.
The erasers were thought up by design company Peleg Design.
