Dual-Unit Hand Percussion Rhythm Set

Two coordinated rhythm shaker units built for synchronous or independent play. Each unit consists of a seamless ABS plastic shell (non-porous, easy-clean surface) and a continuous loop of tightly wound synthetic fibre rope — tested for tensile strength and knot retention under repeated dynamic load. Weight distribution supports fluid wrist articulation and reduces fatigue during extended use. Suitable for rhythmic grounding exercises, auditory-motor integration practice, and live acoustic layering — particularly valued in UK-based Steiner education, dementia-friendly activity programmes, and indie folk ensemble rehearsals.
