Size: 8x3mm-200Pcs
These magnets are perfect for cosplay projects. I use them in helmets, and the size works great—small enough to fit discreetly but strong enough to hold parts securely. You get 200 magnets for a great price, making this an excellent value. Highly recommend for anyone working on costume builds or DIY projects.

I bought these to embed into a 3D print. Glues can come loose. Plus it just looks nicer to me to have them completely built into a print. So have a consistant size is key. Very powerfull, four magents embedded will hold multiple sheets of paper to a fridge and not move easily.

How I arrived at my overall rating: *** (3.5 stars rounded to 4) Value **** (4 stars) Purchase price: $10.07 Was a good price compared to comparable magnets Quality/Durability **** (4 stars) Duration of use: They do scratch kinda easy, but I didn't break any of them. Make sure to SLIDE them apart to avoid breaking. Ease of Use/Assembly/Install: ** (2 stars) For my application, They just didn't work as I thought they would. I mounted them on wood to make a resin knife holder. Testing it on wood was fine, held up the knives. I then tested it with varying thickness of cardboard in front of it to see how thick of a resin I could pour over. Found the correct depth, then poured the resin over. Final product came out nice, but the magnetic strength just wasn't strong enough for my project. Ended up having to drill out holes and putting magnets on the surface and then sealing. Usefulness/Appearance/Fun Factor: **** (4 stars) They could be good for other projects, just didn't work for mine.

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.
