Discover pleasure that moves with you.

The B Ball Uno by Fun Factory offers a refreshingly natural sensation thanks to its internal weighted ball, which responds to every step, shift, and sway of your body. Instead of traditional vibrations, this clever design creates subtle, rolling stimulation that feels organic, intimate, and quietly exhilarating.

Designed with comfort and confidence in mind, the tapered tip allows for easy insertion, while the smooth, body-friendly material and flat base ensure a secure, comfortable fit you can enjoy for longer periods. Fully waterproof and discreet enough to wear under clothing, B Ball Uno is perfect for curious first-timers or anyone looking to explore a new dimension of anal play - whether at home, in the shower, or out and about.
