This little monster knows nice work when he sees it.
The design prints at around 1 1/4" x 1 1/4" and is professionally made with deeply etched rubber so you get a clean stamp that will last through many, many compositions, spelling tests, and extra credit.
You're purchasing one of the "Nice Work" design. Other designs are available as well as several sets of 4 different designs each.
Great gift for teachers and teachers-in-training.
