40mm Thick Steel Cockring — Metal Fat

A solid steel cockring with a 40 mm inner diameter, designed to fit snugly at the base without compromising comfort. The thick width of the ring distributes pressure evenly across the area, resulting in a firm but sustainable compression over time.

Surgical steel, zero compromise

Mirror-polished stainless steel glides smoothly and doesn't retain odors. Unlike silicone, it doesn't deform—the pressure remains constant from beginning to end. It cleans in 30 seconds under hot water and can be sterilized. A ring you'll keep for years without it moving an inch.

The compression that changes everything

The principle is simple: the ring restricts venous return, which maintains blood flow to the penis. The result—a firmer, more voluminous, and longer-lasting erection. With a 40 mm inner diameter, you get sustained compression suitable for average builds. If you're unsure between two sizes, measure your diameter at rest with a flexible tape measure: 40 mm corresponds to a circumference of approximately 12.5 cm at the base.

The weight that makes the difference

With approximately 200g of steel around the base, you constantly feel the cockring. This weight gently pulls downwards, adding passive stimulation during intercourse or solo play. It's a sensation that silicone simply cannot replicate—and it's often what makes guys return to steel after trying it.
