Fun Factory SMARTBALLS DUO is a 74 g twin-ball Kegel trainer made from silicone & ABS. Each ball contains a small free-moving weight that rolls & bounces as you move. The shifting load makes the pelvic-floor muscles respond to movement inside the trainer, adding resistance to squeeze-and-release exercises or walking with the balls inserted.
The 2-ball shape engages muscles toward both the front & back of the vagina. A tapered tip helps with insertion, a groove near the base helps with positioning & the silicone retrieval loop provides a secure point for removal. ABS side panels transmit more of the rolling movement through the outer shell, making the internal rumble easier to notice.
SMARTBALLS DUO is available in Black, White/Pastel Lilac or White/Grape. Customers who find a longer twin-ball trainer unsuitable may prefer the shorter SMARTBALL UNO.
Size guide: All 3 colours use the same 74 g trainer. It measures 6.61" overall; the 2 balls measure approximately 1.26" & 1.42" in diameter.
