The Leonardo Micro Mini Puffy Pawprint brass imprinter (brass stamp) has a pattern head of 6.5mm and is 5 inches long. The imprint is a tiny raised paw print on the surface of the glass. It can be used anywhere on a bead and are small enough that you can place a few imprints on a bead or just make small beads for sets or even head pins. The sample imprint looks different on various colors of glass. We are currently designing new patterns and will offer them when available. The imprint designs are custom made here in America and have been tested for durability, quality and excellence. Beads not included. There is also a 13mm Puffy pawprint available.
