Maybe you're training up your/your partner's butt for bigger things to come, or maybe you're just looking for a great 3-in-1 plug kit. Either way, the Kink collection's 3-Piece Trainer Set has what you and/or your anal enthusiast partner needs to stretch, stimulate and satisfy.If you're just beginning to explore the potential pleasures of butt play, start with the smallest (Medium) silicone Trainer. Feel free to move up to the Large and Extra Large plugs from there, or stick with the little one, it's completely your call!Classic in shape, the sleeker tip of each Trainer swells gradually outward to a largest point near the bottom. A nice long neck helps hold the plug in place as the widespread, up-angled base fits comfortably between your/their cheeks. That base also helps protect against any too-deep slips- a definite plus when it comes to anal penetration.In hypoallergenic silicone, each Trainer is extremely hygienic, cleaning easily using warm soapy water or a good toy care fluid/foam- they can also be boiled, bleached or run through the dishwasher (top rack), if you like. Always enjoy a great quality water based lubricant with these plugs, silicone formulas should be avoided, as should contact with other silicone and soft toy materials.* Measurements provided represent the XLarge Trainer. The Medium measures approximately 4"/10.2cm in total length, 3.75"-9.5cm insertable and 1"/2.5cm in diameter.
