The Fun Factory B Balls Duo offers an innovative approach to pelvic floor training by combining effective exercise with pleasurable sensation. These weighted Kegel balls measure 13 cm in length with a maximum diameter of 4 cm, making them well-suited for beginners and experienced users alike. Their dual spherical design creates subtle, natural motion inside the body, which intensifies muscle engagement more effectively than static alternatives.

Crafted from premium body-safe silicone, the B Balls Duo are hypoallergenic and soft to the touch, ensuring comfort during extended wear. The tapered tip allows for smooth, easy insertion, while the flat base guarantees a secure fit without discomfort or slipping. Their waterproof IPX7 rating means they are safe for use in the shower or bath and simple to clean—just rinse with warm water and unscented soap.

These Kegel weights support pelvic floor strengthening, which can improve bladder control, enhance intimate sensations, and boost core stability. Designed for discreet, all-day wear as well as partnered play, they adapt to varying lifestyles and needs. Backed by Fun Factory’s 25-year warranty, B Balls Duo provide reliable durability and long-term value for users seeking both fitness and fun in one device.
