Balls made of TPR material, waterproof, elastic, with internal weights and grooves for extra stimulation. They have a diameter of 3.5 cm, connected by a string, and the distance between them is 7 cm. The balls are used for sexual stimulation and simultaneously help in strengthening and exercising the pelvic muscle when placed in the vagina. During orgasm, the muscles contract rhythmically, and the stronger the contraction, the more intense the orgasm becomes. The internal weights of the balls move with motion, enhancing the muscles and providing a satisfactory orgasm. It is recommended to clean them after use with a disinfectant or special cleaner for sex toys and ensure they are dry before storing them.
