JOYDIVISION POTENZDUO

Potenzduo is JoyDivision's cock ring line and almost everything on the shelf is a classic non-vibrating ring: no motors, no cells, nothing to charge. Most are silicone, with one in softer TPE, and half the pages carry a phthalate-free declaration. Sizes are the useful part, quoted as internal diameters of 3.5 cm, 4 cm and 4.5 cm, which is a real ladder rather than a single one-size-fits-most. A ring should sit snugly without pinching and should slide off without effort; if it does not come off easily, the next size up is the right answer. Silicone rings stretch and recover well, and they should be washed and dried fully before storage.
