12 Pack Strong Neodymium Magnets, Powerful Permanent Rare Earth Bar Magnet with Double-Sided Adhesive, Heavy Duty Magnet Bar Flat Neodymium Magnets for Kitchen, Tool, DIY, Office-40x10x3mm

It is really strong, so use with caution.

They are small but very strong. They attract to each other and are therefore are difficult to separate. I broke one trying to separate them. However, they are powerful. Held up a metal rack for hanging utensils. There are many uses especially for small spaces. I'm presently looking for a place to hang my knives using them. I wholly recommend them

Am using this for hold downs in CO2 laser. They work really well securing items to the honeycomb tray. Be careful, they can get your fingers. When done, I always gather them up and place the plastic pieces between them for storage and easy re-use. Definitely slide them off the stack. Don't try to pull them.

These are really strong little magnets but as the manufacturer says, if they snap down against each other or onto a metal surface they can break. I would say "they will break". The problem is that they are so strong that if you get them near each other they will pull right out of your fingers and snap together unless you have them in a VERY tight grip. The same thing can happen if you are putting them on a piece of metal. I put one of them on my desk about 6" away from the pile of other magnets and it jumped over and the two that hit both broke. However, they warned me so I can't complain too much.

Used these to fix the problem of being under powered for an opening mechanism on a secret door in a custom cabinet built. Routed them in 3/8 below surface in walnut, and any metal object now pulls open the little door. Simple, quality, affordable.

These are very strong but they break easily.

The perfect size and strength to replace a shower door magnet. Just used some epoxy to fasten it to the door frame.

super fragile, breaks in small pieces!
