These long blocks are amazingly powerful. They will pinch fingers very hard if they are not handled with the respect they deserve. Two of these magnets are virtually impossible to separate by hand. These blocks should only be purchased by persons experienced in handling large neodymium magnets. Be sure you know what you are doing before ordering. THESE ARE DANGEROUS!
