For centuries women have used Ben Wa or Geisha balls to stimulate and exercise their internal muscles, giving amazing sensations and toning up their pelvic floors.

These Duotone balls from California Exotics work in exactly the same way - a small, heavy ball inside wobbles and moves the larger outer ball around inside you for wonderful sensations - try wearing them out for a little added frission, or wear them during oral sex! Materials: plastic, Size: 3 cm x 3 cm, Power: None Required
