Powerful Neodymium Bar Magnets, Rare-Earth Metal Neodymium Magnet, N45, Incredibly Strong 33 LB Strength - 60 x 10 x 5 mm, Pack of 8

They are exactly as stated very powerfulPerfect for my needsas stated in write up on product pageHandle with careWARNING - The bar magnet is very fragile, it is forbidden to collide with other metal objects (including another magnet), so be careful when you are trying separte them !

I see lots of silly people reviews about how they break and blah blah blah. That's just how it is. Your not going to find strong and durable ones. They are minerals not metal. Coat them of put tape over them. Do not click them together, they are not toys or for kids. They will pinch a kids skin in a split second. I use them in my pocket to keep my keys, change/coins and lighter together in a lump so nothing falls out of my pocket. It also helps taking stuff named above out of my pocket.Some money coins are not attracted to any magnetic. Silver coins will only slightly stick to them. Buy the smaller ones for fridge magnets. These are tough to get off. Great on a string in the tool room blah blah blah. Not a toy.

They are not kidding when they say these are STRONG. I pinched my fingers when trying to pull these apart to put on the fridge, and wow! These definitely could hold up a nice stack of papers with no issues.Pros:1) these are small and yet powerful. These are the perfect fridge magnets as they can hold up all your kid's artwork, but they are not ginormous and clunky. they have a nice, compact bar design that works. I love this.2) silver is a great color, and these don't scratch easily. I love that these can be bumped up against each other, and they don't have gouges taken out of them, etc. Yes, I definitely rubbed them against each other a couple of times when getting them out of the box and pulled apart. No damage to anything.3) I suspect these will last for a bit. I am not hugely concerned these will lose their magnetic power. This is primarily due to the material they are made from; but also because it seems to be higher quality upon visual inspection, and initial experience.Cons:1) I would not let kids use these unless you are into seeing your kids have blood blisters on their fingers, or screaming like mad when they pinch their fingers for the millionth time. I know at some point my daughter will get pinched by these. I hope she learns the first time because it HURTS when you get pinched by these! Man, what a bummer it is that these have to be kept out of reach of children, or at least should be if you have that kid who has to try everything.All in all great magnets, but they definitely are for adult use only!

they will shatter and crack against themselves or hard surfaces. be careful. they are very strong.

Complete and utter garbage. While connecting a couple of the magnets together, one broke. This morning I find the magnets had managed to snap together during the night, probably wrong from a fan or the cat brushed against them, they snaped together with one another, and in doing so all broke. I definitely would not recommend purchasing this product.
