Toothed silicone cockring Ø 25 mm — Fitz M8

Silicone cockring combining maximum tightness and generous thickness — 25 mm inner diameter + 20 mm thickness. The profile for those who want to feel the pressure on the base of the penis with a strong physical presence around the balls. Size 55×55 mm.

Tightness + Thickness Combo — Maximum Effect

25 mm inner diameter, one of the tightest in the range, and 20 mm thickness, one of the most generous. The combination results in a cockring that presses firmly on the base of the penis while distributing pressure over a large surface. Firm erection effect guaranteed, marked delay in ejaculation.

Gradual Application Required

The tight 25 mm requires gentle application: stretch the silicone by hand as much as possible, slide one testicle in, then the other, then move up to the base of the penis. Water-based lubricant helps. If you have a generous build, aim for the M5 (28 mm) or M4 (30 mm) instead.

55×55 mm Size — Wider Exterior

The exterior size (55 mm) is slightly larger than standard models (50 mm) — more visual when the ring is in place, more present to the external touch. Hypoallergenic Crazy Bull silicone, washable with soapy water. Usable in the shower for morning prep.

For Users Accustomed to Tight Cockrings

Model 8 — not for first-time use. If you already know your comfortable cockring size and want to increase the intensity, the M8 is the option. For slender builds, it's the pronounced tightness that is appealing. For larger builds, it's too tight.
