## Description

The compact 12 mm magnet helps you quickly sort magnetic, iron-based items from non-magnetic metals while you’re handling jewellery or scrap. Each magnet attaches to a key ring for handy access on the go. The set includes two magnets and a black velvet pouch for storage.

## What matters most

These keychain magnets are designed to show whether an item responds to magnetic attraction. That makes them useful for a quick first check when sorting jewellery, plated pieces, scrap metal or antiques: iron-based materials are magnetic, while materials such as gold, silver, copper and aluminium are generally non-magnetic. The response is a sorting aid, not a confirmation of a piece’s metal content or precious-metal purity.

With two magnets in the set, you can keep one with your everyday keys and place the other in a bag or toolbox. The included black velvet pouch gives you a dedicated place to store the magnets between uses. Compared with carrying bulkier testing equipment for a quick magnetic check, this keychain format is easy to bring along for shopping, sorting or workbench tasks.

## Size & fit

Each magnet measures 12 mm in diameter and 40 mm in height. Its keychain format is made for carrying with keys, a backpack or a belt loop, so it can stay close at hand when you need to check an item. The set comes in silver, with a black velvet pouch for storage.

For example, an antique buyer can carry one while visiting a market and use it to check whether a metal fitting is attracted to the magnet. A recycler or jewellery dealer can keep the second one at a sorting area, making a quick magnetic check available in two places. The magnets can also act as magnetic hooks on suitable ferrous surfaces, such as a refrigerator, tool cabinet or iron shelf, for hanging keys or small tools.

## How to use it

Bring the magnet close to the item and observe whether it attracts. Attraction can help identify magnetic, iron-based material in a mixed batch, no attraction is consistent with many non-magnetic metals, including gold, silver, copper and aluminium. Since different metals can share the same magnetic response, use the result as a preliminary sorting check rather than proof of what an item is made of.

Keep the magnet on a key ring for travel or at a work area for routine sorting. When it’s not in use, store it in the included pouch to help protect it and keep it together. On a ferrous surface, the magnet can also hold small items such as keys or tools.

## Before you decide

**What can these magnets help test?** They can help distinguish magnetic, iron-based materials from non-magnetic materials. This is useful for a quick check of jewellery, plated items, scrap and other metal objects, but does not establish metal purity.

**Can I carry one with my keys?** Yes. Each magnet is designed as a keychain magnet and can be attached to a key ring, backpack or belt loop for convenient access.

**What comes in the set?** The set includes two 12 mm keychain magnets and one black velvet pouch for storage.

## Is it worth it?

For jewellery dealers, antique buyers, recyclers and hobbyists who need a portable magnetic check, this set offers two carry-ready magnets for use in different places. Its practical advantage is straightforward: keep a quick way to sort magnetic items close by, whether you’re travelling, working at a bench or organizing metal objects at home.
