FUN FACTORY B Balls Duo

Move with it. Let it move with you.

The FUN FACTORY B BALLS DUO is a weighted anal beaded plug designed to create a deep, responsive sensation without motors, batteries or buttons. Inside each rounded chamber sits a freely moving weight that rolls, bumps and shifts with every change in rhythm, turning the natural motion of your body into a subtle surge of sensation.

The tapered double-ball silhouette allows for gradual insertion, while the flexible connector and slim, secure base are designed for comfortable wear during solo exploration, couples play or a more adventurous ride. The faster you move, the more pronounced the internal pulse becomes—quiet, discreet and entirely controlled by you.

Crafted from non-porous, body-safe materials, B BALLS DUO is waterproof and easy to clean. Its smooth finish, balanced weight and movement-responsive design make it an ideal choice for those ready to explore a fuller, more dynamic style of anal play.

Use with a generous amount of water-based lubricant for a smoother experience.
