DIYMAG 1" キューブネオジム磁石、最強 1inチ キューブ希土類磁石 - 2 グレードN52、パック

Very strong magnets. But as other reviewers have stated, be careful with them. They lasted about 5 mins. While I was showing them to my daughter (my daughter loves science), I accidentally let them smack together (they were too strong for my fingers). This caused them to shatter a bit and cut my hand. Strong is an understatement for these. I wish they came coated in a silicon sleeve or something.

I knew I was buying strong magnets. I bought the larger ones thinking they'd be safer because I didn't want to buy magnets small enough that a pet or child could swallow them. I didn't read the reviews because they're magnets, what's there to know. Silly, silly me. These are packaged with a small plastic ring between them. In theory to make them easier to separate. This did not work for us. I was having a hard time getting them apart initially & brought them to my son, just to show him how strong they were before I tried again. Well, he couldn't help but try & while he technically got them apart, it was only for a second before they slapped closed again without the metal ring. I took them to a table edge & tried holding the top one tight & sliding the bottom straight down (as pictured, though, I hadn't looked at the picture. Could have used directions In the package, not just on the website). This was working, but suddenly it slipped & they slammed back together, with some of my skin stuck between the two. I managed to rip it off my skin, losing a minimum of skin in the process (but some). Tried again & got them apart. The decision was made that we'd never keep them anywhere near each other. One was set on the counter while I was holding the other a good, 8-10inches away. I moved the magnet I was holding to the side, and the other one jumped of the counter & slammed back into it's twin so hard there was a huge spark & an edge broke off one of them. They're separated again. One is on the side of the fridge. The other is in it's original box, in a closet, in another room. I very nearly threw one away. Just to avoid someone not realizing & putting them together again. They're exactly what they promise to be.

These 2 magnets have a very strong attraction to each other. Had one in each hand and they pulled out my hands which were about 6 inches apart. They snapped together and broke. The outer coating is very thin. Not worth mailing them back for a refund. Beware of the manufacturer/seller.

right out of the package, I caught my finger between the magnets, and BOY DID IT HURT! but I guess that's what happens when you fool around with strong magnets. besides that, they work wonderfully!

I bought these magnets for my 7 year old grandson to use in his magnetic science experiments. These two magnets are pretty much 1 inch cubes, which are similar in size to some Minecraft style blocks, and I thought they would be OK to use with them in addition to his experiments. The package arrived overnight with my grandsons name on it, along with other magnetic products for him to use. He was so excited to see the items I had purchased for him and especially these cubes. Here are the issues with them. These are definitely as advertised, and the strongest magnets I have ever had. These cubes are so strong that it took me over 10 minutes trying to figure out how to get them apart, or if they even came apart Once getting them apart, and the strength I had to use, I was very concerned that they could hurt his fingers if they got caught between them, seriously. After I finally pried them apart, I was showing him how strong they were by placing the Styrofoam they came in between the two cubes and how they still stick together through the Styrofoam. I was reluctant to give them to him to play with, but he was very persistent. I gave him one cube to play with and see how strong they were, but he wanted both cubes. As soon as I gave him both cubes, within seconds, their magnetic attraction was so strong that it yanked the second one out of his hand and they snapped together with such force that the corner of one magnet shattered into very sharp shards. OMG. These are so dangerous and are not toys or for use in science experiments like the description says. See the attached pictures of what happened. DO NOT PURCHASE THESE FOR CHILDREN.
