Inside the Set, you'll find everything you need for lots of amazing foreplay, including a sexy, super soft black vibe with lots of versatile curviness and a matching vibrating ring, both packing twelve remote-optional modes of vibration into their petite, travel-ready shapes. Each piece of the Foreplay set is ready to rock and/or roll all on its own thanks to built-in control buttons, but both can also be controlled using two included remotes. NO BATTERIES REQUIRED. Both remotes are 100% USB charged. 100% waterproof toys. Battery life is up to 2 hours when fully charged.
