Spicy Japanese balls

The main purpose of the Japanese balls is to strengthen the vaginal muscles using Kegel exercises. They can also be used for stimulation and gratification. These cute balls have a relief structure and are made of TPR material, which is completely safe to use. The circumference of one ball is 3.5cm, and they are composed of 2 balls in a row. Each ball has a weight that moves as it moves. For easier penetration, you can use a water-based lubricant.
