The Leonardo Snowflake 2 profile brass imprinter (brass stamp) has a pattern head of 12mm long and has a 5 inch long handle. It can be used anywhere. 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. Sample not included.
