Rare Earth Magnets, 20x3mm Small Round Magnetic 30 Pack

They are packaged nicely and easy to separate. The backing is on the magnet so it’s easy to apply to the item you want it on. I’m very satisfied with magnets. I recommend this product and the supplier.

Small and strong--I'm using them to hold tools in organizers (router bits, Allen wrenches, etc). Glued into recesses in molded or 3D printed holders, they keep the tools in place during handling and give them up without much struggle. Pretty much what I was looking for.

Strong magnet. Great for various projects. Strong. Holds a large capacity of weight. Overall a great value!

These magnets magnet like you would expect a magnet to magnet. They either magnet together or if you would rather you can turn one of them over and let them magnet apart.

These were smaller than I was expecting, and not quite as strong as I thought they would be, either. However, they will be good for many different things, so I'm glad I got them anyway.

I thought these would hold a decent amount of weight but they do not. Because they are so small, it is easy for them to slip out of place. They do hold together as magnets are supposed to, but are not very strong. I do, however, like how all of the magnets come in a carrying case and that you get a lot of magnets for the price.

Very strong for their size! They were used to attach netting to steel benches in our family room.

Ordered the 6x2mm. Calipers show most of the magnets coming in at 1.6 - 1.7mm. Enough of a difference from the stated measurement that I can't use them for my project. A few of the magnets were chipped. These magnets would probably be fine for generic use or where the dimensions aren't too important, would not recommend if using for a project that requires accurate dimensions or strength.
