Blue Silicone Double Cock Ring, Size S — Potenzduo

Two blue silicone rings in different sizes — one for the base of the cock, one for the testicles — designed to work together. The Potenzduo technique: the larger ring circles the cock, while the smaller one isolates the testicles. Controlled pressure, a firmer and longer-lasting erection.

Two rings for two functions

The idea behind Potenzduo is simple: one ring at the base of the cock slows venous return. Combining it with a second ring that isolates the testicles adds another dimension — the pull creates an extra point of tension that intensifies sensations and delays ejaculation. More complete than a classic cock ring.

Soft silicone that does not pinch

Both rings are made from soft shape-memory silicone — they stretch as you put them on, return to their resting size and have no sharp edges. You can wear them comfortably for 20–30 minutes without discomfort, and remove them in one movement if needed. Matte blue colour, non-porous finish that can be sterilised.

Size S: a snug feel and a well-veined erection

Size S has more restricted internal diameters, for anyone wanting a real feeling of tightness without discomfort. If you have never used a cock ring, choose size M first, then move to S if you want a more pronounced effect. The stretchy diameter still makes it easy to put on.

Ideal for a firmer erection that lasts longer

The double-ring mechanism, for cock and testicles, works on blood circulation and the pull on the testicles — two factors that can genuinely intensify erection and delay ejaculation. Use solo or with a partner, and put it on before a full erection to make fitting easier.
