These TRYMAG keychain magnets may be small, but they’re definitely mighty! Perfect for anyone who works with brass, metals, or just has a habit of dropping tiny screws under the couch, these magnets latch onto metal with the enthusiasm of a dog spotting a squirrel. They’re lightweight and compact enough to clip onto your keys or tool bag, so you always have one on hand. The strong neodymium power means they won’t give up on their metallic mission easily—they’ll cling to anything metal like their life depends on it, making it super satisfying for DIY projects or testing. But beware: their love for metal knows no bounds, so if you accidentally drop one, it might just make a break for the nearest metal surface. Pros: portable, strong grip, and handy for small projects. Cons: very easy to misplace, and they can be a little too clingy with anything metallic nearby.

Hooked on my work key ring so I can activate the E-Band monitors used for Transport. It’s works great. Plus it makes it easy to check different metals when not working on the clock. It is also a very strong little magnet, can use it to hang my keys eye level in the shop.

I purchased these to test doors in house to see if they were metal or wood and use them to test jewelry for precious metals. They worked very well for what I needed them for. I felt they were strong for their size. Fast delivery.

The light works good but the stand isn't good you have to put like a weight or something on it so it doesn't tip over

Good value
