Master Series Mega Magnetize Stainless Steel Magnetic Cock & Ball Ring

The Master Series Mega Magnetize is a stainless steel cock and ball ring that opens and closes with hidden magnets, so you can put it on without squeezing everything through a solid loop. At 9 ounces it's deliberately heavy, giving a steady downward pull that you feel the whole time you wear it. It suits anyone curious about metal rings who has been put off by the fiddly fit, as well as experienced wearers who like weight.

Why a magnetic closure helps

The usual problem with a solid metal ring is getting it on and off. It doesn't stretch, so you have to feed everything through it while soft, and taking it off later can be awkward. The Mega Magnetize avoids that. Strong magnets hidden in the band hold it shut, and you open it at the seam, place it around the shaft and balls, and close it again. The edges near the closure are rounded, so the two halves don't pinch skin as they snap together. If the ring ever feels too tight, you pull the halves apart rather than wrestling it off, which makes it a far less daunting first metal ring.

Weight and how it feels

At 9 ounces, this ring has real heft. Once it's on, it creates a steady downward pull on the balls that many wearers enjoy for its own sake, a feeling somewhere between a cock ring and a light ball stretcher. The 0.6-inch-thick band spreads pressure evenly, and polished steel feels smooth and cool at first before warming to body temperature. During sex, the weight moves with you and adds a gentle tug on each thrust. If you've only worn soft silicone rings, expect it to feel very different: more noticeable, firmer and more present.

Sizing a metal cock and ball ring

The inner diameter is 1.75 inches (45 mm), and the outer diameter is 3 inches. Because steel doesn't stretch, sizing matters more than with a silicone ring. Measure around the base of the shaft and behind the balls together while soft, using a strip of paper or string. An inner circumference of about 5.5 inches suits most people, which is why 45 mm is the common starting size. If your measurement comes close to that, the ring may feel tight once you're hard, so keep the first session short.

Using it safely

Put it on soft, with a little water-based or silicone lube on the skin. Wear it for 20 to 30 minutes at most, and open it straight away if you notice coldness, numbness, pain or a dark colour change. It can be used with a pump: pump first, then close the ring at the base. Because it contains strong magnets, keep it away from pacemakers or other implanted devices, as well as bank cards and phones.

Cleaning stainless steel

Wash it with warm water and mild soap or a toy cleaner, paying attention to the seam where the magnets meet. Dry it thoroughly before storing. Steel is non-porous and nickel-free here, so it won't hold odours and suits people who react to nickel.
