G. Flex Thai balls are made from soft, flexible, body-safe materials. They feature a series of balls of varying sizes that extend from tip to base. These balls start with 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, youll find a flexible ring for safe and easy removal when youre finished. Remember to use your favorite lubricant for easier use and double the enjoyment, and clean them after each use.
