The Vater StickMate Tambourine slides right on to your stick, brushes and mallets to give you added sound effects while playing. They're made of lightweight polymer and their low profile won't interfere with your playing. There's a cut-out in the handle for your thumb to rest in and contact the stick. You can easily put the StickMate Tambourine on and take it off. Or, tape the StickMate Tambourine on to your drum stick's grip for extended usage.
