A naughty little secret that will prime your sex drive, Joanna Angel's Spiked Duotone Balls are special weighted ben-wa balls with lots of texture. A striking black-on-pink color makes them look as sexy as they feel, and as you slide these firmly nubbed balls inside, you'll shiver with every bump. Each ball has an internal sphere that moves with each movement of your body. Each ball is connected to a cord for easy removal, and this sex toy is waterproof for easy cleaning. A larger girth makes these sex toys more suited to those already experienced with ben-wa balls. Color: Black, Pink Type: Ben-Wa Balls Material: Jelly Circumference: 4 3/4" Weight: 5 oz (in package)
