How to use it — and who it’s for

How to use it. Get slightly hard first, then ease the ring on — one testicle through, then the other, then the penis. It restricts outflow for a firmer, longer erection. Keep wear time to about 20 minutes and remove it if anything feels numb, cold, or looks discoloured.

Is it right for you? For anyone wanting a firmer, longer-lasting erection — solo or partnered. Start with a stretchy, adjustable style that’s easy to remove.

About this material — Thermoplastic Rubber (TPR)

TPR is a soft, flexible, skin-like blend valued for a realistic feel. It’s more porous than silicone, so clean it thoroughly and consider a condom when sharing.

Care. Clean well before and after, dry fully, and use a water-based lube.

FAQ – Frequently Asked Questions

How do I properly care for the rings after use?

Since the material is a high-quality Thermoplastic Rubber, it is important to clean your rings thoroughly after every use to maintain hygiene. Always check your rings for any signs of wear and tear, and ensure they are stored in a cool, dry place away from direct sunlight.

What kind of lubricant should I use for the best experience?

To keep things smooth and comfortable, we always recommend using a high-quality water-based lubricant. This reduces friction against the skin and makes the application of the rings much more enjoyable.

How can I best utilize this expansion kit with my existing gear?

This expansion pack is perfect for increasing customization by allowing you to stack the two additional square donuts with your original Boner Kit. These rings are designed to integrate seamlessly with your existing gear.

What are the dimensions of the rings?

The ball ring has an exterior dimension of 1.3 by 1.3 inches and an interior dimension of.9 by.9 inches. These dimensions are key to how they stack.

Brand

Sport Fucker

Sport Fucker is Curtis Thompson's line under 665 Brands, making stretchy men's fetish gear — rings, ball stretchers and plugs in soft polymer rather than leather or steel.

Worth knowing before you buy: the range is a genuine mix, and it matters. The signature pieces use a proprietary liquid silicone in firmer and softer durometers, but several items — including some rings and stretchers — are TPE instead. TPE is porous and can't be sterilised; the silicone can. The material is listed per item, and it's the first thing to check here.
