TRYMAG Keychain Magnets for Testing Brass, 2 Pack Neodymium Pocket Keychain with Strong Magnetic Rare Earth, Gold Silver Jewelry Test Magnet Hanging Keys Holder

What a pleasant surprise! These four magnets are just perfect. They come in a small plastic box that closes, keeping the magnets secure. They are plenty strong enough and have little removable rings to grab onto or hang somewhere. I’m impressed.

Powerful and compact. Helpful item.

This is a nice product. I have used it on my jewelry to see If I real or plated necklaces. The adhesive is very sticky and I like the small, in your pocket size. Nice design. It works great as a stud finder. Find a stud and it sticks to the wall.

I needed this for checking gold and silver coins from my collection. It works wonderfully and it's nice and small, which will be handy for going metal detecting!I highly recommend

Good enough and easy to carry

Not as strong magnetism as some other small magnets I own, but this is a good quality product. I use these all the time as a fire alarm tech, to test detectors. The Keychain is convenient for keeping the mag handy or attaching to a pole. They could be stronger, as I have others that are, but for the price to get 4 of them, its a good value.

Excellent. Powerful, easy to slip in your pocket

Worked great

Exactly what I needed for testing silver

前に購入した時の物と先端のサイズが変わっていました今回はケースも付いてません。仕事で使いたかったのですが大きすぎて使い物にならないので残念です

Good a small very useful.

Fairly strong, works well.

Great for testing for ferrous metals when out yard saling/thrifting. Reasonably strong. Also, due to strength, you can get a general idea of percentage.The only downside is that it sticks to your keys. But, whatchya gonna do 🤷‍♂️
