These stamps are about an inch in diameter. These are self inking so you don't need to carry a stamp pad with you. The sayings on the stamps are: "Do it again", "Come on!", "Progressed", "Very Good", "Great". The only thing I don't like about the stamps is unless the surface is very flat and only a couple layers deep at most the stamp doesn't stamp evenly. But otherwise, I think these are great stamps!
