This set of three Chinese balls of Satisfyer are developed with different weights to strengthen the muscles of the pelvic floor. The balls are made of medical silicone and have a small ball inside, which collides with the walls of the vagina. This causes involuntary contractions of the nearby muscles and promotes blood circulation, natural lubrication and muscle tone. They are recommended for all sensitive skin types, including sensitive skin. The set includes three balls, weighing 57, 73 and 86 grams respectively. They have an ergonomic design, so they are very easy to use. For them to be effective, it is recommended to wear them while the person is on the move. Thanks to the discretion they offer, in addition, they can be worn comfortably at home, to go shopping or anywhere.
