FUN FACTORY B Balls Uno
The FUN FACTORY B Balls Uno transforms everyday movement into a subtle internal rhythm. Instead of relying on a motor, its freely moving inner weight rolls and shifts as the body moves, creating a responsive sensation that changes with every step, tilt and change of pace.
Its compact silhouette begins with a smooth tapered tip for a more gradual introduction before widening into a rounded body that creates gentle fullness. Measuring approximately 7.3 cm long with a maximum diameter of around 3.4 cm, it offers an approachable size for beginners and developing users.
A broad, flattened base helps keep the plug securely positioned and provides a dependable point for controlled insertion and removal. Once comfortably in place, the weighted interior responds naturally to movement, producing anything from a soft rolling sensation to a more noticeable pulse as the pace builds.
Made from smooth, body-friendly silicone, B Balls Uno is waterproof, non-vibrating and entirely battery-free. There are no settings to manage, cables to connect or controls to interrupt the moment—only quiet, movement-led sensation guided by your body.
Compact, discreet and thoughtfully balanced, FUN FACTORY B Balls Uno is designed for solo exploration, partnered play and those curious about a different kind of wearable pressure.
Use with a generous amount of high-quality water-based lubricant for a smoother introduction and more comfortable wear.
