The cork lacrosse ball is the perfect complement to massage rollers. It is particularly useful for massaging parallel muscle lines, such as in the thoracic and lumbar vertebrae. The double ball is also useful for addressing muscle tension in the upper thigh and sides of the body. The small ball measures 6.5 cm. By maintaining the distance between the balls, the massage is even more effective. The ball is ideal for addressing tension along the muscles of the thoracic and lumbar spine. By breaking the tension at the trigger points, the entire muscle relaxes, facilitating regeneration and accelerating the healing of injuries. The balls are made of cork, which allows for massage even on slippery surfaces and facilitates maintenance of cleanliness from point to point, on all areas of the body. It can be used on a table, on the floor, or against a wall. - Material: Cork - Diameter: 7.3 cm - Length: 15.5 cm - Hardness: 70 - Maximum load: 320 kg
