StazOn is a solvent-based stamp pad designed for decorating non-porous surfaces such as glass, metal, shrink plastic, cellophane, aluminum foil, leather, and acrylic. With StazOn, you'll achieve a beautiful "stained glass" appearance, due to the transparent nature of the ink. Thanks to its mild smell, it is much safer to use than other permanent inks. It's also much easier to use since there is no need to re-ink the pad before each use. For everything from industrial projects to garden art and home decor, StazOn is sure to become a classic! Stamp pad measures 2 3/4 in. x 3 3/4 in. x 5/8 in.
