The WePlay Twister is designed to provide tactile stimulation and improve circulation. The set comes with 3 levels of resistance, each in a different colour, which gradually help build grasping, twisting and squeezing strength. The tactile surface enhances the sense of touch and promotes wrist joint flexibility. Holding, pressing and twisting the Twister also helps stabilize emotions. Size: 6.2 x 3 x 7 cm. Ages 3+.
