This is the standard basic Mister B Leather Cockstrap, adjustable with 3 snap studs.
Made of sturdy jeans leather, this leather cockstrap is lined on the inside for extra comfort. Because the undersides of the bottom snap studs are covered and stitched in the soft leather lining, no metal parts touch your sensitive skin or can cause irritation.
Depending on what setting you put it, the resulting inner diameter of this cockstrap varies between approximately 40 and 50 mm, ensuring a nice snug fit around your dick.
Having this cockstrap around your dick and balls will lead to longer and harder erections which you (and / or your partner) will enjoy.
