This dual-sided massage roller features a round head with multiple smooth, black massage beads embedded in a natural wood-finish base, designed for targeted myofascial release and acupressure therapy. The ergonomic wooden handle provides comfortable grip and control during self-massage sessions on back, shoulders, arms, legs, and scalp. One side offers dense bead clusters for deep tissue stimulation, while the opposite side (implied by '双面' / dual-side) likely provides broader or varied pressure points—ideal for relieving muscle tension, improving circulation, and supporting post-workout recovery. Constructed from durable wood and high-density ABS or resin beads, it’s lightweight yet sturdy for home or travel use. Includes a bonus acupoint chart (as shown in image) to guide precise application on key meridian points. Perfect for daily wellness routines, yoga practitioners, office workers with neck/shoulder strain, and anyone seeking drug-free pain relief. Non-electric, silent operation ensures discreet use anytime, anywhere.
