OUR EXPERT’S REVIEW

The B-Ball Uno offers a different sensation from a textured plug: its surface is smooth, and the single weighted ball inside rolls as you move. Its 3.4 cm diameter makes the size easy to judge.

The Fun Factory B-Ball Uno houses a free-moving spherical weight inside its smooth silicone body. It rolls in response to every move you make, without a motor or conventional vibration. This compact black butt plug measures 7.9 cm in total, including 6.5 cm insertable, and 3.4 cm at its widest.

A weighted ball that moves with you

The stimulation comes from the free-moving ball inside. Walk, roll your hips or change position: as it rolls, it creates natural pulses, without external texture or a motor.

An easy-to-insert tapered shape

The tapered tip and smooth exterior make gradual insertion easier. Its maximum diameter of 3.4 cm is still manageable if you're a beginner or want a discreet plug to wear while moving around.

Smooth silicone, a comfortable base and safe use

The ergonomic base remains outside and keeps the plug in place. Use water-based lube, then wash it with warm water and mild soap after use.
