These huge blocks *MUST* be handled with extreme caution. These giant blocks are favorites of magicians and illusionists.  They are incredibly powerful and should only be purchased by users familiar with the proper handling of large neodymium magnets. Two of these stuck together are virtually impossible to separate by hand. They can pinch and cause physical harm if they are not handled with extreme care and respect. 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 DANGEROUS!
