NEODYMIUM MAGNETS ARE NOT SAFE FOR CHILDREN Each hook magnet will hold up to 200 POUNDS I have even pushed this to 210 pounds. (Holding strength beyond 200 pounds may vary and is not guaranteed.) See diagram below for optimal hook placement. Use these versatile hooks to hold everything from plants to tools. Hook is removable and can be replaced with other threaded parts. The possible uses are endless! ***WARNING*** These are Very Powerful Magnets! Magnets of this size and strength can pull metals objects to them when brought too close. Two magnets of this size will fly together with great force and can easily pinch fingers and skin. DO NOT allow children to play with these magnets. They are simply too strong. Also, even though these magnets are coated with tough nickel metal, all neodymium magnets can chip and break. The larger the magnet, the easier this can happen. When placing a magnet on metal, try to ease it onto the surface. If it "flys" onto it, it can shatter. Trust me, I know from experience. Please excercise caution and planning when using these magnets and they can serve you for a lifetime (and without bruises) :-) These Neodymium Iron Boron magnets are also known as "Rare Earth" or NdFeB magnets. Neodymium magnets are simply incredible! They are far more powerful than those old horseshoe magnets most of us grew up with.
