Smaller than the original Fun Factory Smartballs, Uno is perfect for beginners.

These silicone vaginal exercisers are easy to insert and, as the company name suggests, they’re fun too! Fun Factory Smartballs feature internal balls that move when you flex, providing a subtle but enjoyable vibration. “Uno” is especially suitable for beginners and women with a dropped or tilted uterus or those who simply want to get their pelvic muscles back in shape.
