Common types include dual foot rollers, handheld rollers with two or four spiked rollers, compact four-node hand massagers, and small solid-wood trigger-point tools such as sticks, balls, and knobs.
Most are made from natural wood or hardwood (for example, beech and maple). Some designs combine wooden frames with rubber or natural rubber‑latex rollers or pads.
Sizes vary from compact handheld models to larger foot rollers. Typical dimensions reported range roughly: lengths about 4.75–11 inches, heights about 1.5–3.2 inches, and widths about 3.5–7.4 inches, depending on the model.
Common features include ergonomic handles or center grips for better control, non‑slip rubber pads or bases for stability, and dual rollers or multiple nodes that make rolling and pressure application easier.
Care instructions vary by item: many list spot‑cleaning or wiping with a damp cloth, some recommend hand washing, and a few note a clear lacquer finish that makes cleaning easier.
Pressure is adjusted manually—users roll back and forth or apply more or less force with their hands or feet. Ergonomic handles or grips make it easier to vary and control pressure.
