Pearl PWR-40 Shakalets. Shakelets are an accessory by Pearl's innovative percussion R&D team that feature exclusive "Ganzinellas", Brazilian-style plantinellas combined with ganza shakers, that are worn on the wrists to produce a shaker sound when playing. Clap your hands, shake them in the air, use them with drumsticks - the uses for Shakelets are virtually limitless. Shakelets are also useful for people living with disabilities to rekindle spatial awareness and to learn right from left. Most of all, Shakelets are just plain fun!
