The njoy Pure Plug is a hand-polished, solid 304-grade stainless-steel butt plug — one of the original premium metal anal toys, in production at njoy since the brand was founded in 2005. It comes in three sizes — Small (1.0"), Medium (1.25"), and Large (1.65") — each with the same essential geometry: a tapered tip, a wider rounded bulb, a tapered neck for retention, and a flared circular base ring that doubles as a pull handle. The product is not pretty in a gentle way. It is heavy, mirror-finished, and unmistakably a piece of medical-grade hardware shaped for a single purpose.

Why It Matters

The Pure Plug is the canonical example of how non-vibrating, "minimalist mechanical" anal toys hold their cult status across decades — even as the category trends toward app-connected, motorized novelty. As doctor-led anal wellness becomes a 2026 retail growth category (per industry analysis), the Pure Plug occupies the "premium evergreen" tier the way the Magic Wand does in clitoral toys.

What makes it special is the material. Stainless steel does what silicone, glass, and ABS cannot: it conducts temperature with no insulation. The Pure Plug can be warmed in a sink of hot water or chilled in the freezer drawer for ten minutes and will hold that temperature for a meaningful portion of a session. The weight — Small 5 oz, Medium 7 oz, Large 11 oz — also creates a passive sense of fullness that no silicone toy can replicate at the same dimensions. Steel is also fully non-porous, dishwasher-safe, boilable, and bleach-compatible, with effectively unlimited service life.

What reviewers and users are saying: Autostraddle's anonymous Pure Plug review, Ace in the Hole, themisskat, and LuxeVibes all treat the Pure Plug as the reference standard in the metal-plug category, and Reddit r/SexToys and r/anal threads consistently pick the Medium as the "buy it for life" plug recommendation. Most cited pros: tapered tip makes insertion smooth even at the Medium size, the loop base sits flush, the weight is "addictive" once acclimated, and any lubricant works including silicone (which would degrade silicone toys). Most common critique: the Large is genuinely large — Autostraddle and other reviewers warn that beginners should size to Small or Medium first, and that the bulb-to-neck step on the Large is steep enough to feel intimidating. The base loop on all sizes is mandatory — it is the only safe-removal feature.

Price and where to buy: Small $89, Medium $119, Large $159 at njoy direct, RodeoH, Babeland, SheVibe, Lovehoney, and other major retailers. eBay and Amazon listings exist but counterfeit njoy plugs are a known problem — buy from njoy or an authorized retailer.

Materials and safety: 304 surgical-grade stainless steel, polished to a mirror finish, no plating or coating. Compatible with all lubricants. Non-porous, sterilizable by boiling, bleach, or dishwasher. Flared base meets every safety standard for anal toys.

The bottom line: The Pure Plug is the right pick for someone who wants a true buy-it-for-life anal toy and is willing to pay metal-toy prices for the temperature-play and weight properties that no silicone can match. Beginners start with Small. Intermediate users land at Medium. Large is for users who already know what works.
