Magnetize-It! F20x4x1mm - Neodymium Rectangle (20 Pack) Magnets

Super strong, well made (smooth, uniform size). Quite fragile. They say dont mess around with them. I couldn't help myself. I would lay 1 magnet down on the table, and see from how far the rest of the magnets would pick it up. Guys it would pick up from like, half a foot away almost. It was crazy. But the force of the magnets coming together would shatter the magnets. Not every time mind you, but in about 10 minutes of playing around I broke like 4 of them. They're smooth, no jagged edges. I'm not a magnet expert, but those were the main qualities I was worried about.

These are very small, but VERY strong!

These are awesome little magnets. Strong, thin, and very useful. Great product.

I was looking for something with a thin profile that would still be strong enough for what I wanted to use them for. I'm glad I found some that came with multiple. These are thin, and I did have a couple of them break pretty quickly before even placing them where I wanted (mostly because the attraction was so strong that it broke when coming back to the main stack). All in all, much stronger than I even expected so that's a bonus. Thinner and more fragile than I expected. Hoping this will still be fine, but I could see these breaking using them the way I will be. I'm still pleased though.

These are very thin, BUT the magnet is very strong on its own. It is easy to apply to anything. These are well worth the price paid. They work better than some other magnets.

These tiny things are strong. I glued them to my bread box door and worked great.

More than half of these broke just trying to get them apart. Yes, I slid them at least halfway off one another before lifting upward/away. I could not finish my project. A few more broke while trying to glue them onto a craft. They are thin but I was expecting more. 2 of 10 remain intact.

They are strong magnets in regard to force of attraction. In fact, the force may be too strong for as thin as they are since 4 bars have already split in half after being pulled back into the larger stack of magnets. This happened maybe a minute after opening the package and not much handling. Hoping I can still use them, but quality seems to be questionable.
