TRYMAG Small Magnets, 400Pcs Neodymium Print Rare Earth Magnet, Black | Tiny Mini Round Magnets for 3D Printing, Office, Kitchen Cabinet, DIY Miniatures, Refrigerator, 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.

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.

Four stars because These are an experiment I’m going to try, by making my NScale RR town structures stay put but removable for transport and storage and for replacing light fixtures instead of gluing them down permanently! Haven’t done any yet but these seem strong enough to hold in place with steel washers glued inside corners of buildings while magnets recessed in 1/4 inch shallow holes.

These are perfect for crafts. Pay attention to the size as they are very small

I was using these for my 3d prints and needed smaller sizes than my normal magnets. These had a great arrange of sizes but for my needs they were way too weak to hold up the arms or even the head of my printed object. I put 3 in an arm and still the strength just wasn't there. I recommend them if you are working with small very small objects and minis. But if your working with 1/10 scale or larger I wouldn't recommend them.

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

These work great for my 3D prints, very strong and the sizes are dead on accurate!

Smaller than expected, but exactly as described. I'm actually pleasantly surprised by how tiny the smallest ones are, as I'll find many unusual applications (embed in my pens, eyeglasses, jigs that need a delicate clamping pressure)

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。

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

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

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.
