Two rings working together changes the whole experience. More sustained pressure, more sensitivity, and you stay harder longer without thinking about it. That is what this setup does for you, and once you feel the difference, a single ring starts to seem like the wrong tool for the job.The dual design gives you a 2 inch base ring and a 1.5 inch shaft ring connected by a leather strap, so both stay exactly where they should while you are in the moment. The nitrile material is the same stuff used in hospital gloves, which tells you everything you need to know about how safe and skin-friendly it is. It is strong enough to hold its shape and do its job, but flexible enough to be comfortable and snap right back after every use. No pinching, no fussing, no wondering if the material is okay against your skin.Spartacus has been making leather and restraint gear for serious buyers for a long time. This is not a novelty item. It is a well-made piece that does exactly what a good cock ring should do, and the nitrile and leather combination gives it a look and feel that holds up. If you want more from your solo time or want to bring something that actually performs, this is the easy call.Product DetailsBase Ring Diameter: 2 inchesShaft Ring Diameter: 1.5 inchesMaterial: Nitrile, leather strapBody-Safe: 100 percent skin safe materials, same components used in hospital gloves
