TRYMAG Magnets 400Pcs Neodymium Print Rare Earth Round Multi-Use Printer Magnet for 3D Printing Craft Fridge DIY Refrigerator Office Kitchen Cabinet Crafts and Science

Really powerful magnets, but BEWARE! i must not have read the description that well - they come in 3 sizes and i thought the size i wanted was the smallest. it wasn't, it was the largest. the other two sizes are very small. they work fine but are too small for my needs.

Got this size because another customer said they got them for the tiny ducks people leave behind on cruises (since they did away with the rubber ducks). They "do" the job, but one little bump and they fall right off. We actually just got back from a cruise, found a tiny duck, and they actually used one size up. (Which is what I thought I was buying.) So, in the end, I would go up one millimeter for the tiny ducks. Again, the ones I purchased DO the job. I just don't like how easily they can be bumped off.

They were the right size and were all magnetically stuck together when they arrived. As they should be... what else can you say?

These TRYMAG mini magnets are excellent for light-duty applications and I have been happy with the purchase. The 4x2mm size is genuinely tiny, which makes them perfect for small craft projects, labeling displays, or attaching lightweight items to metal surfaces. The 240-pack gives you a lot to work with at a good price, and they come in a useful container that keeps them organized. For fridge magnets holding a single piece of paper, these are more than strong enough. For whiteboard and billboard use at lightweight, they hold well. Where they start to fall short is anything with real pull requirements, since the small size naturally limits strength. If you expect to hold multiple sheets or anything with weight to it, you would want something bigger. I also found that they are very easy to lose given the tiny size. One rolled off my workbench and finding it was a small adventure. Just something to be aware of when working with them over carpet or rugs. For the specific use cases they are designed for, these are high quality and the pull strength is impressive relative to their size.

Smaller than I expected but they do the job.

Great value for the money got 400 pieces in three different sizes. I use it for 3-D printing and I was able to add them to my projects. Wish they sold the larger pack.

Strong for the size but ultimately, I need something far larger for my design. These are still fun hobby magnets, and I can think of a few ideas for them with tiny 3d prints.

Probably should have pulled out the old micrometer for the smaller ones because I truly didn't realize how TINY they were. They are not very powerful so didn't quite do what I needed them to do. Not even sure what you would use these smallest ones for as again, not very strong. Glue the largest ones to a stone to stick something on as a display. Could EASILY remove the displayed item from the magnet.

These magnets are fairly good for their size. Not super strong but good for small items.

プラモ作成時に最も消費する 3mm x 1mm を多めに買っておこうか、と購入。 1mm x 360個なら繋げれば36cmになるはずと思って測ったが実際は30cmに満たない。数をチョロまかされたか？と数えて見ると個数は合ってる。 となると厚み。測ったら殆どは0.8mmで±0.5mmほどの誤差がある。全部を測ったわけではない(やってられない)が0.9mmに届いたものはなく、最薄で0.71mm。ざっくりした使い方ならともかく精度を求めるなら役に立たないだろう。 ただ、0.8mm前後の厚みというのは逆に珍しくもあるので選り分ける気があるなら良いかもしれない。

Good magnet, not the strongest, but perfect for what they were bought for. I use them for Warhammer minis and the hold great and on bigger model I just add more.

I use these to magnetize my wargaming minis and they work well.

Work ok
