These licensed stamps are deeply etched and precision cut from premium gray rubber on a 1/8" gray rubber foam backing. Stamp will arrive with a clear sheet of acetate which you remove and a smaller clear fixed plastic which is used to affix to the acrylic block. While still on the acrylic, it is easier to clean. Return the stamp to the acetate sheet for storage and protection.
All sizes are approximate:
