For centuries women have used Ben Wa or Geisha balls to stimulate and exercise their internal muscles, toning up their pelvic floors.
These Black Orgasmus Duotone Balls work in exactly the same way - a small, heavy ball inside wobbles and moves the larger outer ball around inside you, strengthening and toning your pelvic muscles.
Simply insert them gently and let them roll inside you, toning your pelvic floor muscles - especially useful if you've just had a baby and are looking to get some internal definition. Stronger pelvic floor muscles improve orgasm.
Ball diameter 3.5cm. The balls weight 30g each. The string is 5g totalling 65g for the set.
