Double the movement, double the sensation.

The B Balls Duo by Fun Factory are designed to deliver powerful, natural stimulation through motion rather than vibration. Two internal weighted spheres respond to every shift of your body, creating rolling sensations that feel organic, playful, and quietly exhilarating.

The tapered tip allows for smooth, comfortable insertion, while the flat base ensures a secure fit you can trust - whether you’re enjoying intimate moments together or wearing them discreetly throughout the day. Crafted from body-friendly silicone and fully waterproof, the B Balls Duo are easy to clean and built for long-lasting pleasure. Simply add water-based lubricant and let their natural movement surprise you in the best way.
