Ergonomic design with an oval shape for a comfortable grip, allowing training of two fingers simultaneously for improved effectiveness. Features ventilation to prevent stuffiness; raised bumps reduce skin-to-sphere contact, while the center remains breathable to prevent heat buildup in the palm. Finger-splitting design helps address finger adhesion caused by finger contraction in stroke patients and aids in preventing irritation between fingers. Ideal for finger exercises, the grip ball is compact, measuring approximately 6.5 cm in diameter and 10 cm in length, fitting comfortably in the palm. Squeezing the ball provides pressure on the fingers, promoting hand strength and comfort. Repeated use may produce a warming sensation in the palm, enhancing the therapeutic effect as the elastic ball deforms to fill the hand. Note: Color may vary slightly due to lighting and display differences. Size tolerance is ±1–3 cm. Color: Yellow. Size: 10 x 6.5 cm. Quantity: 2 Pieces.
