TRYMAG 40Pcs Refrigerator 8x3mm Small Round Magnets for Crafts, Mini Rare Earth Tiny Strong Neodymium Disc Magnets for Whiteboard, Fridge, Office, Hobbies, Kitchen, DIY

Very thin, very strong, does the job. End of the story..

I can't say all that much about these other than they are a great buy for what they are. They come in a nice little plastic case. It can be a little hard to get them back in the case without some maneuvering, but definitely not a deal-breaker. The only downside is that they can be a little brittle. I did break one. But it's not the end of the world. For the price, I could afford to break a few. These are great. Nothing wrong with them. Very strong magnets. I especially like the fact that you can get a variety of sizes all in one pack. Great buy!

Firstly, these magnets are smaller than I anticipated, but they offer the size on the description; I was too lazy to get up and look for a ruler. Secondly, I have a set of large rattlesnake eggs (magnets that make a buzzing sound when snapped together). I bought more to play with, that are metallic rainbow colored, and they snap together to make a buzzing sound. I also have a magnetic ball that also makes the buzzing sound against the egg shaped magnets. I hold the “eggs” above the ball and it snaps up and makes a sound. I tried this maneuver with a few of the magnet disks, and the top disk broke into four pieces. I also made the same mistake with the long rectangle magnets, and one broke in half and again chipped. The interesting thing about magnets when they break is there is no possible way to piece them back together, once they break. They become polar opposites. That’s too bad, because they would’ve made fun puzzles if they did snap back together. The magnets are very strong. I took two and put them on both sides of my earlobe and they stuck. They don’t stick on both sides of my hand when using just one magnet, but a pair of two magnets - one set on my palm-side-up and the other set under my hand - will promote the set in my palm to flip when I move the set under my hand. Three magnets will barely attract enough to stick on both the palm and top of hand, but if I move my hand, they will disconnect and drop. I cannot take stars for the breakage of the magnets, because it’s not a manufacturer’s defect. There are a couple of dents in the magnets, but even that is, in my opinion, an event expected to occur; it doesn’t effect the function of the magnets. I have a metal desk lamp that I use to hang all my metal pens, and magnetic items on; the pieces that broke still stick to the metal, and can hold metal pens, my nail file, paper clips, safety pins, etc. so it’s not a loss, really. If anything, it taught me an interesting lesson about breakage becoming instantly polarized, and how fragile thin magnets can be. Don’t drop the magnets, and don’t allow them to “jump up” or “drop down” to another magnet from a distance; whether combined with other magnets or by itself. They can easily break. I do have a purpose for these. I like to glue them on items like non-metallic pens, my outlet remote, my pulse-ox case, etc. so I have quick and easy access to my frequently used items that I stick to my metal desk lamp. Yes, it looks tacky. I keep an airtight box nearby to store all these items in on Thanksgiving Day when I invite people over for turkey (except this year). But normally, I prefer convenience over appearance, so these magnets do come in handy. I would recommend these, but I would also warn about the frailty of the magnets.
