Ben Wa Balls on a String Silver

Two Weighted Balls and a Cord

Two balls, one string. The build is simpler than it sounds, and the nylon cord does two jobs at once: it links the balls and gives you something to pull on when it is time to take them out.

The balls are finished in silver and carry a light set of raised nubs across the surface. The texture is subtle. It registers as a gentle sensation when the balls shift, not as firm pressure. There is no motor and no vibration, so everything the balls do comes from their weight and movement.

Weight That Asks Your Muscles to Work

The weight is the main idea here. Because the balls are heavier than they look, your pelvic muscles have to contract to keep them in place. That contraction is what the design is built around, and it becomes more noticeable as you walk or change position.

Movement changes the feel. Standing still, the balls sit quietly. Walking or shifting around sets them moving against the textured nubs, which is where the stimulation comes from. Many people find the sensation builds gradually rather than arriving all at once.

ABS Shells and Nylon Cord

Each ball is made from ABS plastic, a rigid, non-porous material with a smooth finish. The string is nylon, and it stays attached to the balls throughout, which keeps retrieval straightforward.

ABS and nylon are compatible with water-based lubricant, which is the safer choice here. Silicone-based lubricant is not recommended, since it can degrade the ABS. Clean the balls before and after each use.

Length, Width and Fit

At 6.25 inches long, 3 inches in diameter and 1.5 inches high, the set is compact enough to pack easily. The listed weight is 0.31 pounds, so it is light in the hand but noticeably substantial once inserted.
