Christopher Well I think they'll work on certain inks. Unfortunately it's not working for my situation.

Jeanne Paglio I love using these erasers. They take the ink and pencil marks from many types of surfaces without ruining them.

Roger Fairchild They work great for removing graphite from wood for my woodburning projects.
