DIYMAG Small Rare Earth Magnets, 40 Pack, 5 Sizes - Neodymium Magnets for Refrigerator, DIY, Crafts, Kitchen & Office

I bought these for 3D printing projects and have been happy with them so far. The storage case is a nice bonus and keeps all the different sizes organized instead of having loose magnets everywhere. I checked the dimensions with my digital calipers, and they matched the listed sizes. The magnets also have good holding strength for their size and have worked well for my projects. The only minor issue was that one magnet had a small chip on the edge when I opened the package. It didn’t affect its performance, but I hope quality control can be a little better before shipping. Overall, this is a good assortment of magnets with accurate sizing, good strength, and convenient packaging. I’d buy them again.

These are strong, durable, sleek. They do not come with adhesive, so I use E6000 to affix them, and that makes them impossible to remove. There are no sharp edges, they're perfectly smooth and round. I'm happy with this purchase and would get them again. I once ordered a mixed box of these magnets a while back and received about half of the lot as microscopic, 1mm magnets! I had no use for those and was very disappointed, but this size was exactly what I needed. Make sure to read the size carefully before ordering.

I am using these to magnetize a large Warhammer 40k miniature, and so far they have not been a very good showing. While they do hold, they are not as strong as some of the other neodymium magnets I have purchased in the past of similar diameter, but lesser thickness. I had hoped getting thicker magnets would result in a tighter hold. They also don't tend to center the polarization in the center of each disc, and each seems to have a slightly different pole to the next and will often start to repel an opposite pole magnet if you try to use a smaller magnet with a larger one. They'll probably be fine to adhere to your fridge, but if you want them to sit centered with each other you might have better luck with other multi-size magnet kits. They're also quite fragile, though neodymium magnets are naturally very brittle. Some of them came with their edges a little chipped already, making me worry that the magnets in the middle of the stack are already broken. I had one on my desk and moved a drill bit too close and it snapped to the bit and shattered into pieces on my desk. Eye protection is a must for working with these, as those little metal shards getting into your eyes if you accidentally drop one is a very bad thing (you should use eye protection with most hobby projects anyway). I am still going to use the larger size ones for some heavier pieces as long as I can match the disc sizes perfectly and hopefully they'll be able to hold the weight. Update: They do hold weight nicely and worked great on my Imperial knight's arms, but the magnets are still polarized more on the edges than in the center of the disc so they do HAVE to be the same size magnets to really get them to be effective at holding them correctly, so just use the same size magnets on both pieces.

Comes in a convenient plastic case for easy storage. Lots of sizes which are great for different uses. I bought these for craft projects to hold metal stitch markers and Bobby pins and they work super well for my needs. They’re strong and thin, not at all bulky.

8X of each five sizes. The smaller ones are fairly weak, with the larger ones having a bit more pull. But for basic crafts these are fine.

Nothing wrong with these magnets, They have a powerful attraction to each other, but on painted steel they have a very light hold. I think the problem is they are too small to have much pull.

magnets are strong. I’m very happy with them. I love magnets. I don’t know why.

I got these to use keep small screws on drill bit works like a charm saved a lot time. Much more powerful don’t keep near electronics as could damage screen or other compenents.

Item as stated

Great magnets, very strong. I use them for my miniatures so they stick to a metal baking sheet for easy transport.

I purchased these magnets in order to create personalized fridge magnets as favours for a wedding. The largest sized of the magnets do a fantastic job of holding up these tiles and can carry the weight of several papers underneath. However, all sizes under that do not do a great job and slide under the weight. As regular stand alone magnets they work fantastic. They do crack as mentioned in some of the reviews. The smallest size (shown in the picture on the tile that has two magnets) would slide under the weight, but two magnets worked fine and could support papers underneath. The small magnets on their own hold papers well. For my purposes, they were satisfactory and the price point was there to make inexpensive party favours.

Good magnets, break if you drop them tho.
