300 Pack Small Magnets, 4x2mm Refrigerator Magnets Rare Earth Magnet Neodymium Magnets for Crafts, Whiteboard, Kitchen Cabinet

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).

These magnets are super strong! I put them in my pill organizer to keep the boxes open while I refill them, and my washing mashing lid can’t stay up because of the shelving over it but the shelves are metal so guess what? ONE magnet on the dishwasher lid is enough to stick to the shelves above and keep the lid open!

I bought these magnets to put on the back of fuse glass products to sell at my craft show. They are the perfect size and very strong. Glass is fairly heavy in and of itself so I needed a good strong magnet that would not only hold up the weight of the glass, but also a piece of card stock. These magnets do the trick. They came well packaged but one of the magnets was broken. This is not unusual as magnets are brittle in naturally and break easily. Good product, I will buy again.

Tge magnets I recieved are strong and fit my purposes wonderfully. They are consistently sized. The only downside is that a small handful of them seem to be glued/fused together making them rather useless for a crafter, but those are far fewer.

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.

I was new to magnetizing and wasn't sure what to get. Thankfully this set handles all of my magnetizing needs, for personal works and commisions, and I plan to buy more kits in the future.

Great magnets

The description is 4mm x 2mm, their cute picture of calipers show 4.00mm x 2.00mm, and a diagram in the pictures shows 0.16 inches x 0.08 inches, which is 4.064mm x 2.032mm so I was expecting between 2mm and 2.032mm. Instead the nominal size of what I received is 4.00mm x 1.76mm. 0.24 mm too small. This a big deal at this size. 12% less volume makes for substantially weaker magnetic force. Shown is a single example at 1.76mm and 10 taken at random showing a total height of 17.63mm. Several (13 of 300, 4.3% lossage) magnets were defective with voids and chips, 2 pairs were corroded together and there was some metal detritus in the container. One was "extra" undersized at 3.53mm d x 1.8mm h. In total 16.3% less product than promised, and too out of spec to be used for the purpose I needed. This means I'm going to have to source them again, somewhere else, wasting my time.
