12 Pack Strong Neodymium Magnets, 40x10x3mm Rare Earth Bar Magnet | Large Flat Magnetic Strips, Powerful Permanent Rare Earth Magnets with Double-Sided Adhesive for Classroom, DIY Projects

I was really impressed by how strong these magnets are. They really do the job.

These magnets come in a small plastic hard case, with spacers in between each bar to ensure easy separation. Check the directions online before ordering these, since mishandling these magnets can cause injury. Do not purchase these if you're just hanging papers on the fridge. They are far too strong for that purpose.These are not for children/toys. One of these can easily hold a metal refrigerator shelf filled with heavy containers, and even then, it is still difficult to remove. Bringing one of the bars closer to another one causes them to slam together with enough force to make you jump. They will pinch, hard.

Awesome magnets, super strong. Can be used for so many different things. I highly recommend this product.

These are super strong magnets. Kinda difficult to separate if they attach to one another or remove from placement. But they work, that's for sure.

Super strong. Used it to hold ductwork extension in place. Use with caution. They can pinch.

Nice. Good and strong just like I wanted. Decent price too. I'm happy. 😁

My grandson was playing with them and one of them just broke into many pieces. I would never think of a magnet breaking like that .

I have purchased these Magnets a few times. They are good for things from attaching Motion Sensor Lights to making a "Chip Clip" for Kids, or letting them make their own Clips, that adhere to the Refrigerator. They can attach a Note Pad to anything metal and be attached to a rod to pick up metal objects from the floor or narrow space. also good for putting a row of them on a workbench backboard to keep track of Knives, Scrapers, Utility Knives, Etc.
