TRYMAG Small Refrigerator Magnets, 50Pcs Rare Earth Magnets, 10x3MM Black Strong Neodymium Disc Magnets for Fridge, Whiteboard, Billboard, Crafts, Office, Tiny Round Button Magnets

These work perfectly for my needs. I saw numerous mediocre reviews and was somewhat concerned, as we all are these days, about throwing good money for bad on Amazon. No worries here. What are your expectations? They are fridge magnets and are quite strong. For their size, little things, I’m more than pleased. One of these dinky little magnets held a stack with 2 business cards and 3 slips of paper securely to my refrigerator door. Two of them are just extra security. And for the cost, I easily got my money’s worth. They’ll probably perform well for other applications I may need them for.

I've bought 370 of these magnets and have used over 300 of them. The ones from my first order (50pcs) were great; very strong, size within spec and great finish. So I ordered 200 more. Of those, 100 were great, but the other 100 were weak, undersized, had finish issues and you could tell some were chipped before being coated. I'm embedding these in 3d prints and need them to be strong and pretty true to size, so the 100 bad ones were unusable for me. I was disappointed with that order and planned to find another seller, but ended up needing more magnets quickly and these were the only that would be delivered in time. I ordered the 120pcs set and thankfully these were acceptable...but still not great. The finish and size were good and they were decently strong, but not as strong as that first order. In the end I'm not sure if I'll by these again. The black coated ones are less common (compared to silver/nickel) and there aren't nearly as many choices of sellers for them.

These are really strong magnets that arrive flush with Warhammer 40k bases. They are really strong so I would not recommend for anything below 50mm bases and can be easily used for much larger models.

Good

Perfect size and good magnetism
