totalElement 12.7 x 3.2 mm Neodymium Rare Earth Disc Magnets N48 (30 Pack)

Four stars because they really are magnetically very strong. Setting someone the task of pulling a couple of them apart is a recipe for a good laugh as you watch the confidence drain out of the person's face when they realise it's a real struggle.However, these are by far the most brittle Neodymiums I've bought. One broke in two just being placed on a calendar against the fridge. They are brittle enough that the 30 are now 22 after just a couple of months.If you're planning to use them where they'll never be impacted by anything (even very gently) they will be fine but if you're using them in a situation where they will be moved and handled you might want to look elsewhere.

These magnets arrived promptly and were a perfect teaming with a wall painted in "magnet paint", that allows magnets to stick to it. Unfortunately the magnets seem to be very brittle and two have chipped - one badly enough that 25% of one aside has broken off. Handle with care!

So 3 shattered by the time I got them out of the bags. They are ridiculously strong, but fragile!

Excellent magnets they have a really strong pull, just right for what i needed them for, may order some more, very pleased with them

Exactly what it "said on the tin". Product arrived promptly and was ass described. Very strong for their size.

Brought these for a child science party. They hardly lasted, chipped and became unstable very quickly

good

Great price
