BEST CHOICE MAGNETS 500Pcs Small Magnets, 7 Sizes Refrigerator Magnet

I bought this 300-pack of 4×2mm magnets specifically for my 3D printing projects, and they are exactly what I needed. They are small but very strong, making them perfect for "hidden" closures on printed boxes or modular pieces. The consistency in size is great, so they fit perfectly into the holes I design in my slicer settings. With 300 in a pack, I don't have to worry about running out mid-project. If you are a maker looking for reliable rare earth magnets for functional prints, this is a great value.

Great little magnets for tiny magnetic projects. Especially good with 3D printing projects. Small but powerful enough to stick to most things without falling off. Easy to pull off but quite easy to lose as well. The only thing is that they dont have the polarity marked (which most magnets dont) so if you are using them for a project, be certain about the polarity before you commit to anything (ask me how I know lol).

Nice quality and strong will buy again

I make a lot of cosplay props and costumes and very now and then I need some magnets. I ordered the 300 pck, so that's probably a 5-year supply for me:) so, definitely a good value for the money. I think I will probably also buy a size larger just to have in my studio. These magnets are small (I got the 4x2mm) so their strength is relative to their size. They definitely like to stick to each other, but they are just too small to support a lot of weight. I use them to hold visors open, so their power/strength is ideal for that.

These magnets are real nice, strong but NOT strong enough for use through thick fabrics. I am a suit maker looking for magnets to use through faux fur and these struggle a little! The larger the magnet the better the pull and they gave me so few of the largest size

Perfect for wood working and 3d printing projects

Good size and strength for making polymer clay magnets!

Smaller than I thought but will work perfectly to make cover minders for diamond art.
