The Strict Leather Red Speed Snap Cock Ring is made of high quality leather and features 4 snap sizing slots. It effectively holds erections harder and longer, and looks great, too! Can be worn around the penis alone, or wrapped around the balls as well for a more snug fit and increased sensation. All metal is nickel-free. Spot clean as needed. Use a little water-based lube on your shaft and balls to reduce friction during wear, then wrap the strap around your shaft. You can choose to wrap around the shaft only (near the base) or around the shaft and balls (at the base, behind the balls). As you place the strap on, match up the snaps to where they feel the most snug, without it feeling uncomfortable. Then firmly press the snaps into place -without pinching any skin- and secure the ring. Adjust as needed for comfort. Wear for about 30 minutes before removal and enjoy that harder erection! Measurements: Overall length: 8.5 inches, Strap width: 0.6 inches, Inner diameter adjusts from 0.8 inches to 2.25 inches Materials: Leather, metal Color: Red, Black
