The Meinl Cajon ring castanet is designed to create the classic castanet sound whenever you strike a Cajon, djembe, bongo, conga, or any other hand percussion instrument. A sturdy and comfortable strap secures a wooden castanet to your finger for added sounds without having to do any extra work. This handy accessory may also be placed on the Meinl classic Cajon brush (model# CB1) for a castanet sound.
