Oeuf d'exercice jaune (résistance très faible)

Kit Planète exercise eggs are designed to stimulate the muscles of the wrist, hand, and fingers. Their texture is soft and textured, and their shape allows for a stable grip in the hand (5 cm diameter). The exercise eggs can be used as a fidget (stress ball), as a tool in physical rehabilitation, or as a game to develop grip strength in children. They can be squeezed, crushed, and manipulated vigorously without losing their shape or strength.
