The Leonardo Skull brass imprinter (brass stamp) has a pattern head of 13mm and is 5 inches long. This tool has a concave design that allows the glass imprint to look raised or puffy when used. 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 as shown.
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. Bead not included. If you have any ideas for imprint designs you would like to see you can email me at beads@ptd.net
