Choose a stainless-steel butt plug by its material documentation, widest diameter and external base, then check the exact size being sold. A polished appearance alone does not identify the alloy or make an item suitable for internal use. This guide is for adults and focuses on purchasing, care and safety.
The njoy Pure Plug Small and Medium are two identifiable options with a documented stainless-steel product family. Neither is a universal beginner recommendation: rigid metal does not compress, and a smaller size name does not guarantee a comfortable fit. We compare published product information rather than claiming hands-on tests or ranking dozens of unrelated items.
What to check before choosing
- Material: a named manufacturer and a clear alloy statement are more useful than “premium metal” or a silver-colored photograph.
- Dimensions: compare maximum diameter, insertable length and the size of the external base separately. Package dimensions do not describe usable size.
- Retention design: the base or handle must stay outside the body and allow removal. A decorative end is not enough information.
- Condition: avoid products with rough seams, damaged coatings, sharp edges or uncertain provenance.
- Seller: check the selected variant, seller identity, return terms and manufacturer support before paying.
1. njoy Pure Plug Small: the smaller option in this comparison
The Small belongs to njoy’s Pure Plug range, which the brand’s official Australia/New Zealand distributor describes as cast 316 stainless steel with a polished finish. It has a curved body and a separate ring-shaped base. The direct listing linked below identifies the Small, silver version and lists a 0.98-inch maximum diameter, 2.36-inch insertable length and 3.15-inch total length.
Those measurements make the selected item easier to distinguish from the Medium and Large. They do not establish suitability for an individual. Check the dimensions against the actual selected product at checkout, especially if the marketplace changes the title or combines sizes on one page.
Main tradeoff: this is still solid, rigid metal. Someone seeking a lighter or flexible product should compare a clearly documented silicone alternative rather than assume “Small” solves every comfort concern.

2. njoy Pure Plug Medium: a different size, not an automatic upgrade
The second listing is explicitly the njoy Pure Plug Medium, model E22224, sold as one item. Galaxus’s matching E22224 record identifies size M and a 3.2-centimeter diameter, approximately 1.26 inches. It is part of the same polished 316-steel family, but the size difference matters more than the shared name.
Consider it only if the actual measurements and rigid construction suit your needs. There is no requirement to move through sizes, and no basis here for promising a particular sensation, tolerance or wear time. Buying a larger product because its price is similar is a poor substitute for checking fit.
Main tradeoff: the wider body is less conservative than the Small. Marketplace catalog fields can also be inconsistent: this is a non-motorized metal plug, not a vibrator, even if a secondary catalog attribute suggests otherwise.

How to read a product listing without mixing up sizes
Start with the model name and selected size, then look for a measurement drawing. “Length” might describe the full object, the usable portion or even its packaging. Record the maximum width as well as the length; two plugs of equal overall length can have very different profiles.
Read the listing again after selecting a variation. A photo, title and measurement chart should all describe the same item. If they disagree, ask the seller or manufacturer to identify the product in writing. Do not resolve a contradiction by choosing whichever dimension seems preferable.
A larger multipack is only useful when every included item has a clearly identified material and appropriate design. More pieces, high review counts and decorative finishes do not answer those questions. We have deliberately kept this comparison short rather than fill it with anonymous products whose specifications cannot be established.
Stainless steel, nickel and surface condition
The official distributor’s FAQ confirms that njoy’s 316 alloy contains nickel. Do not read “medical grade” or “hypoallergenic” as a promise that a product is nickel-free or appropriate for every allergy. If you have a nickel allergy, avoid assuming stainless steel is suitable; discuss a different material with a qualified clinician if needed.
The same FAQ warns that a household magnet test is not a reliable authenticity check. Instead, retain the product information and purchase from a source whose identity and support you can verify. A familiar silhouette or a convincing storage box cannot establish the alloy.
Base design, lubrication and warning signs
Planned Parenthood’s sex-toy guidance emphasizes that anal toys need a flared base or another effective way to prevent the whole object slipping inside, and that lubricant is important. Inspect the actual base before use. Do not substitute household objects or assume an ornamental handle guarantees retention.
NHS inform notes that anal tissue can be damaged and recommends water-based lubricant; oil-based products can damage latex condoms. Check the lubricant and barrier instructions as well as the product’s own care instructions.
Stop if there is pain, bleeding or irritation. Do not force insertion or removal, and do not treat a shopping guide as advice for managing a medical condition. If you have an existing anal or rectal problem, reduced sensation or recent surgery, ask your clinician before using an internal product.
If a product becomes stuck, seek prompt medical help rather than using tools or another object to retrieve it. The Merck Manual explains that retained rectal objects may cause injury and sometimes require medical or surgical removal. Severe pain or significant bleeding warrants urgent care. Embarrassment should not delay getting help.
Cleaning and storage
Follow the directions for the exact item. For routine njoy care, the official care page recommends soap and water followed by drying with a soft cloth, and warns against abrasive cleaners or pads. Store the clean, dry item separately so it does not knock against other hard objects.
NHS inform advises washing shared toys after use and using a new condom each time they are shared. Nonporous material still requires cleaning. Do not generalize boiling, bleach or dishwasher instructions to plated, coated, glued or motorized products. This guide does not claim that a household cleaning routine creates a medically sterile instrument.
Bottom line
The njoy Small and Medium provide identifiable starting points for comparing stainless-steel plugs. Choose on verified dimensions, material suitability, base design and seller accountability. If any of those remain unclear, resolve the question before buying rather than relying on a long “best” list or unsupported safety promise.
