Onyx: what it is, and what it isn't

Two different things share this name, and search engines can't tell them apart. Let's do both properly, starting with the one we actually sell.

Onyx Pinnacle — £64

Onyx Pinnacle Silicone Butt Plug. Anal → Butt plugs.

Three things make it a good first plug, and none of them is the price.

It's manual. No motor, no charging, no buttons. When you're learning what a sensation feels like, a vibration pattern is one more variable getting in the way of the information you're actually after. Manual means you set the pace entirely.

It's genuinely waterproof, not splash resistant — so it goes under the tap, and because there are no electronics in it, a 100% silicone plug like this can also be boiled for a few minutes to sterilise it properly. Almost nothing else in the anal department can say that.

The base is unambiguous. 25 mm insertable with a clear flared base. That base is not styling: the rectum draws objects inward and there's nothing at the far end to stop them. Every insertable in our anal department has a flared base or a retrieval loop, which is a stocking rule rather than a preference. If you read one other page before ordering, make it silicone anal toys and flared bases.

Cheaper alternatives, same idea: Dusk Taper and Fern Taper are both £17.95. The vibrating step up: Serene Anchor, £139, remote controlled — though note it's wipe clean only, not waterproof.

The condom question

We don't currently sell condoms, under the Onyx name or any other. Our Essentials department covers lubricants, cleansers, storage and body care — there's no condom range, and we'd rather say so than let you hunt through 77 products finding out.

Since you're here, the part worth knowing anyway:

Thin doesn't mean weak. Ultra-thin latex condoms meet exactly the same burst-pressure and leakage standards as standard ones. The material is thinner; the testing isn't different. If sensation is the reason you're shopping, thin is a real improvement and not a safety trade-off.

Latex allergy has good answers. Polyisoprene feels closest to latex and is the usual swap. Polyurethane is thinner and conducts heat better but is less stretchy. Both protect against pregnancy and STIs. Lambskin does not protect against STIs — the pores are large enough to pass viruses — and is worth knowing about only so you can avoid it.

Oil ends latex. Coconut oil, massage oil, body lotion, petroleum jelly: all of them degrade latex fast enough to cause failure during use. Water-based or silicone-based only. The lubricant guide has the full table.

A condom over a toy is a legitimate technique. It makes cleanup trivial, it's essential if you're sharing a toy between people, and it's the only reliable way to use silicone lubricant with a silicone toy without wrecking the toy.

Free condoms are available from sexual health clinics across the UK and from many GP surgeries, and under-25s can get them through the C-Card scheme in most areas.
