FINDMAG 20pcs Strong Neodymium Magnets, Heavy Duty Rare Earth Magnetic Bars, Rectangular - 40x10x5mm

These arrived in a little plastic box with a snap-closure lid. The magnets are very cleanly made with no sharp edges or pointy-corners. They have a uniform finish and no evidence of any chemical residue or smell. They are strong for their size but are NOT advertised as "SUPER" magnets. I feel that the ad is 100% accurate and this is easily a repeat-purchase item. Buy with confidence.

I have no complaints, I'm happy with these.I have been fidgeting with neodymium magnets for over a decade.These were cost-effective for the volume of magnetic material. I bought these on sale for $11.99 for a pack of 20, I entered the dimensions in a spreadsheet I made and these have the second lowest price (per cubic millimeter) among about 20 different magnets I've entered. Even at $14.99 they're still top five for price per volume.These do feel quite strong, even though I haven't done specific measurements.They come in a little plastic box sandwich between two pieces of foam. I had two of them stuck outside the box with the rest of them in the box when I actually dropped them on concrete. Not a great strength (brittleness) test but none of them appear to be damaged. Based on past experience I had predicted at least one of them would have broken in half. Most likely one of the two on the outside.

Magnets that work pretty good. Do not let these slam together, they WILL break and chip. I put these in my 3d prints and have little to no issues other than the questionable brittleness of the magnets.

Magnets were very strong and worked perfectly for the use I had in mind.

I had objects that I wanted to make sure they would stay put, and they do.

The magnet are great, they are small and strong however I was shortage 3 or 4 magnets in every shipment and one magnet was broken.

The media could not be loaded. OK so I have a lot to say about these. You can use them for literally anything. For me the number one thing was for my curtains. And for solutions to south and west facing windows. in the first two pictures I show my bathroom which lets in in the late afternoon a lot of light which is a lot of heat especially being on the second floor this is just something quick I can put up in the summer months it takes two seconds. And then I take it down clip them together and put them behind my bathroom door attached to the metal hinge it just sticks right to it out of sight out of mind everything looks beautiful. The third picture is my bedroom I have used them to keep the curtains clipped together in the middle and on the AC. I used to use a pant hanger. The fourth and fifth picture picture and video is my kitchen. I have a curtain there for when I'm cooking to prevent smells from going to the rest of the apartment. These magnets have just made the curtain look more presentable. Most corners have that metal piece on top of the sheet rock it sticks right to the wall. The last bunch of pictures are my office. I love my white curtains and do not want to get blackout curtains but in the summer in the late afternoon this room gets very very very hot. So I had left over black out travel curtains that I tried to use for my bedroom but it failed so I stored them away for two years and thought that I could attach a magnet to one side and the other side and then put them on my blinds because my blinds are metal. The picture does not capture how much darker it is and less heat is coming through. But it is a significant amount! Significant! I attached it with the blinds completely closed and then I attached it also with the blinds closed a little bit so that it covered everything but either way either option it's still helping with the sun in the afternoon on my west facing windows. And I get to keep my white curtains up. I am also away a lot and do not want my apartment heating up while I'm gone or having to run the air-conditioning while I'm not home so these are perfect solutions. These magnets are amazing. I'm in life and I ordered more I don't know what I'm gonna do with them yet but I'm excited to find out!!!

very strong for a small magnet
