I like a clutter free fridge. With one of my kids in school and the daily art projects being brought home, these magnets were a game changer. I also like using these magnets to hang up photos on the fridge. Makes for a clean sleek look. The reason for 4/5 stars for "easy to remove" is because if you have acrylic nails, these magnets are hard to grasp. Without my acrylic nails, I had no issue removing these magnets. Overall very satisfied.

There are many brands of Neodymium Magnet for sell online. This one is by far the strongest!

See pics. Advertised size is 3 x 12 mm. Actual size is 2.4 x 11.8 mm. What matters is thin magnets break more easily. I have denoted 3 x 12 mm magnets that are actually 2.8 x 11.8. Much closer to the nominal size advertised. I only ask for honesty in advertising but this seems to be the norm. If you say it enough times people believe it. DON'T BELIEVE THIS VENDOR'S DESCRIPTION. IT'S NOT ACCURATE.

Strength is quite good but not as strong as the expected size, they are 10% undersized which may matter for your use-case. Diameter is spot on 12mm, but thickness was only 2.7mm averaged over 10 items, I ordered 12x3 and that’s what’s on the box so ow have to adjust my designs.

They are 12x3mm like it says, but weaker than expected. Had a 3d print model that used 6x3mm magnets that wasn't working well enough so I resized the holes to 12mm and the random 6mm magnets from a kit were working better.
