rhinocats400Pcs Small Magnets, 4 Different Sizes Tiny Mini Magents, Multi-Use for Fridge, DIY, Office, Hobbies, Crafts and Science

Awesome magnet. I love the variety of sizes and usability this product offers. Have purchased more for hobbies i have. Great price and quality

Ordered these for random 3D printing projects and it's great to have a number of different sizes for all projects. I've only utilized them in a few but they've been great. Strong and simple, they work nicely in any random project that needs that magnetic connection. High strength stuff.

Good magnets works well and strong tinier than I thought but perfect anyways

These magnets are amazing! Very strong,perfect sizes for everything I needed,only downside is they are a little chunky

Super strong. Love the case it comes in for storage too. Magnets all come together but they are easy to separate and work as expected

Perfect little crafting magnets. 2 sizes. Super tiny and Super super tiny. Smaller than I thought they’d be, but I don’t mind. Great price too. And they work great on my ceramic pieces to create fridge magnets.

Strong magnet's.

I bought these for use in my 3D Printing projects to remove the need for having to connect parts with 3d printed latches/hinges/etc. I was hoping to find square but found these instead and the price was right (I think under $10). Now I cannot stop thinking about magnets. I've made several designs using them, ended up needing a few of them for items that I lost the magnets for while building, and also just have fun in general using them like little fidget toys. I ended up buying another pack of just the 6mm because those are pretty strong. Definitely going to be getting more.They work well when directly connected. All the things I used them in hold well and can usually find each other pretty quickly as long as there isn't too much in between them. Using the 4mm magnets, I've been able to get sometimes 4mm distance between them. This is while making a hole in my 3D Prints to be able to push them in, so about 2mm on each part connecting. Even when them enclosed in a pocket, they still hold well, but the 6mm seems to hold the best. Your best bet is to keep stacking them if you need more strength out of them or to go to bigger magnets if you aren't able to get the hold strength you need after about 4 or 5.
