This is a wallet insert, the exact same size as a standard credit card so that it will perfectly fit in any wallet... for man or for women. It is a thick 20 gauge copper that is not easily manipulated. Whatever you want stamped, can be put on the wallet insert... if it will fit. This is my top selling item, and can fit any gift giving occasion. We also seal all items before sending them out, so it will remain the new shiny copper color and not tarnish like a penny.
