Keychain Magnet for Testing Brass,Keychain Pocket Magnets for Purse with Strong Magnetic Rare Earth Neodymium,Gold,Silver, Jewelry,Ferrous Metals Test Magnet and Hanging Keys Holder D12mm

These are very good, strong magnets for this specific type of metal—if you're unsure whether an item is made of gold or gold-plated steel. It's a nice little gadget, and the holder is attracted to everything except gold and gold alloys.

These are so important to have! The CDC website (and others) have said not to have Silver or Gold Tone Metal touch your skin. The Cadmium (and even Lead, etc.) are in most cheap metals. I tried to find a way around it, but in the end my life is more important to me than buying, making, selling or wearing inexpensive jewelry. I got a lot of my jewelry making supplies out of my house and I hated it at first, like I said, but I am much happier now knowing at least that no one I love is wearing it. If they want something, I will make it for them free of charge. There’s a law in my state but right now, only for children, since it’s such a huge market it may not see the light of day for a long time, unfortunately. Children are more likely to put the jewelry in their mouths, so it’s really good that it is taken seriously. I have seen lots of jewelry making supplies say Stainless Steel now and much of it I have tested isn’t. It’s really good to have these metal testers (and some other types are worth it as well with these if needed) and they have worked well for me so far. Think about metals around you and having this is a good start. I feel better having these since I put one on my keychain and one in my room, so that way if I want to test something while I’m out I have one handy. I know it will continue to come in handy too. Thank you…

Great magnet for testing metals worth money. It looks nice and slim and once it attaches with something it’s hard to pull off works very well. I would recommend.

Very strong. I hunt for sterling silverware whenever I get a change. This is easy to carry with me.

These are very powerful little keychain magnets, Im not sure I would keep it in my pocket so that I don't inadvertently damage an electronic component or magnetize something I don't want to. Perfect for retrieving something by putting it on a long string!

I have had these for 5 months and they are excellent. They just went through the washing machine and still work as if new.

These magnets are fairly strong for their size. Useful for all sorts of stuff around the shop. The keychain loop makes them awesome for hanging stuff up, though i mostly use them for retrieving stuff and determining if iron is heated up hot enough.

Keychain was made very good, magnet very strong. I highly recommend this item, delivery was fast.

They are small but mighty! Good quality, strong, arrived fast and in good condition. I am keeping one at home and one in my purse to use it when on the go, shopping. Highly recommend.

magnet are strong

These are very nifty little magnets. Small enough to have in your bag or pocket, really cool design. I am so happy with this purchase. If you are in need of a small magnet I highly recommend these. Really great value.

Handy and small. Good packaging. Recommended to test coins.

Definitely a great strong magnet. You can easily tell when a piece of jewellery isn’t of good quality. helps to distinguish metal from silver.
