Only 1.47" at its largest diameter, this plug is a good intermediate toy - larger than a beginner piece, but easy to hold & a gentle stretch. The Ryder has a gradual curve from the body to the neck of the plug, which means it won't shock the sphincter muscles going in or coming out. The anchor base helps the Ryder stay put comfortably. Made from Tantus’ own unique formula of 100% Ultra-Premium Silicone. Eco-Friendly, Hypoallergenic, Hygienic, Boilable, Bleachable and Dishwasher Safe. Diameter: 1.47"Length: 4"
