The Spiky Ball Line Sport sensory ball is a compact yet extremely effective tool for precise massage and therapy, ideal for working on smaller parts of the body and hard-to-reach places. Thanks to its small diameter of 7 cm, it works great in relieving muscle tension around the feet, hands, neck and calves, while helping to strengthen muscles. The protrusions on the ball's surface intensively stimulate tissues, supporting circulation and regeneration, making it an excellent choice for active people, athletes and those looking for an effective way to relax and loosen muscles on a daily basis.
