These are fantastic for everything from fridge organization and office tasks to DIY crafts, hobbies, and science experiments. It’s no wonder they are marked as "Amazon's Choice" with over 5K bought in the past month the value for money here is incredible. If you need strong, small, and reliable magnets for your 3D printing projects or miniature crafting, this mixed 400-pack is an absolute must-have!

These magnets worked perfectly for what I needed! I attached them to little clay figures I made and they hold really well. The magnets are actually so strong that they can be a little hard to pull apart or remove, but that’s definitely a good problem to have! I wanted something that would stay securely in place and these absolutely do. Great quality and perfect for crafts!

If you've ever found yourself staring at a magnet and asking the universe how it works, this 400-count mixed pack from RHINOCATS won't answer that question philosophically — but it will give you more tiny magnets than you'll ever need to test the phenomenon personally.Four sizes (6x2mm, 5x2mm, 4x2mm, and 3x2mm), 100 of each, all strong for their size and consistent in quality. The nickel coating keeps them looking clean and rust-free, and the variety means you're not locked into one dimension for every project — great for 3D printing closures, craft work, DIY builds, or anywhere you need a small but reliable hold.The magnet strength genuinely surprises for how small these are. They're not going to move mountains, but for embedding in printed parts, securing lightweight panels, or any application where you need a discreet, low-profile hold, they perform well above their weight class.Now, do they hold more things than the entire Faygo lineup? Absolutely. Can they help you understand the miracles of the universe? Unclear. But for roughly three cents a magnet you're getting a versatile, well-made bulk pack that will cover your needs across more projects than you've probably planned for yet.Magnets. Miracles. Whatever. Five stars.

Great option with multiple choices to choose from! Easy to add to items, super strong magnets! Love the size options! Fits great!

Very strong magnets that are difficult to use because they want to connect to their friends when trying to install.

These D6x3mm neodymium magnets seem to work well. I use them for 3D printing projects, and they seem to be plenty strong in terms of magnetic strength. I would say get this if you've ordered magnets from rhinocats and you know you'll go through your supply of magnets quickly. Both the diameter and thickness of these magnets seem to be relatively precise enough - well, maybe the height might not be as precise, but usually getting the diameter of holes for magnets in 3D printing models is more crucial than the thickness. If anything, they might be slightly thinner in height than the specified 3mm height. Otherwise, the overall size of these magnets are more or less precise and accurate.

Im using these in toys and functional parts for my 3D prints and boy howdy do they satisfy my need for magnets. They're more than strong enough for my needs. If you need stronger magnets, get ready to pay big time for it...

Good Strong Magnets, Perfect for 3D Prints. I've made a few things with these, one being the hangman game in book form. These work great. Good tip on installing it to keep them in a stack. Add your glue to the hole, press in the magnet, and pull sideways to release. Makes for a super fast install. When installing the opposite side, go back to the original magnet, flip the stack over, and make sure you feel it repelling rather than connecting. This way, when you install them, they are installed correctly, with the repellent side down, in the glue.

Fantastic magnets, small enough and strong enough for my DIY and CRAFT needs.
