This glass dilator kit is designed with a true understanding of how the four sphincter muscles actually work — along with the skin and nerves layered over them. It’s shaped with real anatomy in mind, including the natural variations in length and structure from body to body. Because when it comes to the back door, the details matter. This system of small, medium, and large rectal dilators relaxes and strengthens backdoor muscles, enhances skin elasticity, and ensures gradual, safe training. Great for for priming or play, solo or with others. Materials:Made from body-safe, shatterproof, non-porous Borosilicate glass. Hypoallergenic and phthalate-free.
