The Fun Factory B Balls Duo are a thoughtfully designed pair of weighted kegel balls measuring 13 cm in length with a maximum diameter of 4 cm, perfectly crafted for pelvic floor training and intimate stimulation. Their two spherical weights create a natural internal motion that mimics the body’s rhythms, offering more nuanced sensations compared to traditional vibrating devices. This makes them suitable for both beginners focusing on strengthening pelvic muscles and experienced users seeking intensified stimulation during solo or partnered play.

Constructed from smooth, body-safe silicone, these kegel balls feature a tapered tip for seamless insertion and a flat base that ensures comfortable wear throughout the day without discomfort. Their waterproof IPX7 rating expands usage options to include shower or bath environments, and cleaning is simplified to warm water and mild soap.

Ideal for users aiming to enhance sexual wellness, improve bladder control, or add subtle pleasure discreetly, the B Balls Duo provide a versatile solution that balances comfort and effectiveness. Backed by a 25-year warranty, these kegel balls promise durability and long-term use. For the best experience, pair with a water-based lubricant to aid smooth insertion and maximize comfort.
