These amazing blocks are some of the strongest neodymium magnets available anywhere. They are extremely powerful and must be handled with great caution. They can pinch very hard or even crush if you get between two of them or one and a piece of metal. They are heavy, sturdy, and unbelievably strong. Once this large, flat block is attached to a metal surface it will be pretty much impossible to remove it. This magnet is not a toy!

You must read and understand our Neodymium Magnet Safety Page before ordering these magnets. You must also agree to our Terms and Conditions prior to purchasing. THESE ARE VERY DANGEROUS!
