Review on Powerful Neodymium Magnets: Unleashing the Strength of Earth's Elements by James Wiley

These things are so strong that when I walked into the house from the garage, I had all the magnets in my hand, walked through the (metal) door, and they flew right out when my hand was right on the door stuck ! LAUGH OUT LOUD! wowzer! As you can see from the photos they come with double sided tape and a plastic spacer to keep the magnets separate and easier to remove from the stack (luckily!). I'm telling you, these little ones are strong! I had one in one hand and a stack in the other, a separate one flew out of my hand and crashed right into the stack about 5-6 inches from it. totally surprised me! This happened several times. They are thinner than a year ago when my parents bought magnets of the same brand but in packs of 10. Not sure if it was because they were in a stack of 10 and I had 20? I do not know? But they don't break as easily as my parents did. None of mine broke accidentally, it's a couple of times and my parents did (and they have thicker magnets, not much) so I'm not sure if it was accidental or what? Recommend these magnets for DIY projects with safety in mind.
