TRYMAG Small 10x3mm Rare Earth Magnets, 50Pcs Strong Neodymium Tiny Round Fridge Magnets for Whiteboard, Refrigerator, DIY, Kitchen, Office

Strong for their size, works well for 3d printing projects.

I bought there to attach to ornate mini picture frames to hand on my fridge and they haven’t budged.Strong magnets

The size works for one use, but not another. I used these under miniatures for transport and they are a perfect size and strength. They’re not quite strong enough for GW scenery though.

These things are actually seriously not a joke. SUPER magnetically strong. Like, they're quite difficult to pull apart. Unless you have something ridiculously thick you are trying to pin to your fridge, then there is no chance that these magnets will fail to hold your paper(s) to it. No chance. And the bigger the size you choose, the stronger you're going to have it. I just wanted to have some of the smaller ones, but i'm quite impressed regardless.

These are tiny, but they're great magnets, I use them to hold my race bib when I go running.
