Knurled Steel Cock Ring for Penis and Testicles 55 mm

The largest diameter in the knurled series — 55 mm, made for larger builds or gentle compression around both shaft and testicles. The knurled outer texture and black inserts give this ring a raw, industrial style that stands out.

Textured knurling, smooth inside

The outside is machined with a diamond pattern — a rough texture that stimulates a partner's skin at the slightest contact. The inside is mirror-polished to glide across skin without friction or irritation. This contrast between a raw exterior and a smooth interior is the signature of this range. The black inserts add an aesthetic detail that evokes a piercing/industrial style.

Large size for comfortable wear

With an inner diameter of 55 mm (around 17.3 cm in circumference), the ring slips on easily and applies light compression. The effect is subtler than in the smaller sizes, but the congestion remains noticeable — especially in the testicles, which are held forward. It is a practical size for long wear or for first sessions with a metal cock ring for the penis and testicles.

Durable steel, compatible with everything

The 140 g of stainless steel give you a constant sense of presence without discomfort. Compatible with all lubricants, sterilisable and guaranteed not to deteriorate over time. A ring like this is something you buy once and keep forever.
