These rings are the proven choice for rock-hard erections that last and last. With two super-soft silicone rings to choose from, this is the perfect starter set to help you achieve your maximum potential. Made from body-safe Elite Silicone, the thick rings can be used together or individually. Once they’re comfortably around the base of your shaft or balls, they gently restrict blood flow to help you achieve the biggest, thickest, and most intense erections. The ring's tight squeeze will put a clamp on embarrassing midway performance letdowns. Small ring has 1.1 in. inner diameter and large ring has 1.4 in. Lotion and toy cleaner included.
