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

I bought these 4x2mm magnets thinking, “How strong can something the size of a lentil be?” Answer: strong enough to reorganize my life and occasionally jump off the table like they saw a ghost (aka another magnet).Highlights from my new magnetic lifestyle:Turned my fridge into a museum—mini prints, notes, and a shopping list that no longer swan-dives to the floor.Found a lost screw in a carpet that eats hardware for breakfast. Victory.Labeled spice jars, cable-managed a rat’s nest, and made a tiny whiteboard pen holder that’s cuter than it has any right to be.Built a magnet “snake” that hypnotized my cat and, briefly, my spouse.Things I learned the hard way:They will snap together from across a small country. Keep fingers, credit cards, and dignity clear.Drop one? Drop ten. Sweep the area with another magnet like you’re panning for metallic gold.Store them stacked, or they will reproduce in the wild (science might disagree, but my desk says otherwise).Bottom line: Small, mighty, and weirdly addictive. If your vibe is “organize everything and also play with shiny clangy dots,” this 300-pack is perfect. Five stars—just don’t blame me when you start magnetizing household objects that didn’t ask for it.

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.

So, these are very tiny, but I was extremely happy to find such small magnets for a particular craft my family did. These worked perfectly, they were strong enough to hold up what we needed them to do, and small enough to be hidden. I could imagine using them for a variety of different, small crafts.

A few magnets deformed and/or chipped, but overall good strength for the size.

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.

Very happy with assortment of magnets. Has a clear plastic case to keep them in and the various sizes will work very well for many crafts and other things. Very satisfied with this.

This is a nice set of small magnets—and are impressively strong! Perfect for all kinds of craft projects, DIY tasks, or even organizing small items around the house.

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.
