Our friends at Tenga have made a new and improved sleeve-style toy that features more detailed internal sculpting than ever. Expect enhanced sensation from all the soft ridges and angles inside, plus strong vacuum sensation from its special one-way valve: after insertion, squeeze the pressure pads located on the top and bottom of the Zero for focused stimulation as well as suction. Fans of insertion sleeves know lubricant can add way more pleasure, too—either drip lube into the opening before penetrating, or open Flip Zero up completely to drizzle your favorite brand along the entire interior. The easy-open/close design also facilitates getting the toy completely clean and dry. With Zero's seamless insertion point, expect an improved seal that helps minimize pesky lube leakage during use. Clean with mild soap and water; allow to dry completely before storing.
