Fun Factory heard your feedback. The B Balls are loved but some people wanted a smaller version. The B Ball Uno has one hollow ball with a smaller, weighted bead inside that moves when you move, thrust, or through using a vibrator! A slim, comfortable base keeps the plug inserted safely. Made of 100% silicone and ABS plastic in Germany. 

Insertable Length: 2.36" (6 cm)

Width at widest point: 1.26" (3.2 cm)
