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.
