G. Flex Thai balls were made from body-safe, soft and flexible materials. They are fitted with a series of balls of different sizes that move from the tip to the base. These balls range from a small ball at the tip, for a perfect and extra-secure insertion, gradually increasing in size to the largest ball at the other end. At the end, you will find a flexible ring so you can safely and easily remove them when you are done. Dont forget to use your favorite lubricant for easier use and double the pleasure and clean it after each use. Features Flexible Thai balls, increasing sizes, body-safe materials
