My son needed some magnets for some 3d prints/builds. Some serious magnetic attraction. The sizes fit perfectly into the printed holes. Not to tight that it was a struggle, but a nice snug fit. I did have one break (as the packing slip warned) after letting 2 magnets get too close, and they snapped together from several inches apart.

Great magnets tjey are perfect for warhammer 40k

I never like to write reviews, but after reading some of the other reviews, almost all of them were positive, but one was indicating that the magnets were not strong enough this could not be father from the truth. In the description from the seller, it stated exactly what the product was in detail, and it was spot on, if you’re looking for a very strong magnet. You will not be disappointed. Sometimes people say I guarantee it but obviously, I am just a purchaser , but if I could I would.
Ps. Thank you Total Element 👍🏼

Works perfectly, arrived quickly and as advertised.

Good variety but some magnets arrived damaged. Good price
