Review on DIYMAG 40X20Mm Super Strong Neodymium Disc Magnet, Permanent Magnet Disc, The World'S Strongest And Most Powerful Rare Earth Magnets - One Piece by Aaron Vang

I liked the size as they are small enough to handle and strong enough to have some serious fun with. Sorry they ran out and hopefully they will purchase another batch and sell them again for this price range. Due to the strength of these magnets it would be nicer to have at least a 3/8" thick Plastic Spacer/Separator between the two magnets. Also package in a stronger Card Board Box (heavy duty card board) Using the foam holder and end caps so that the magnets are isolated from other magnets and or a ferrous metal . To make a very strong magnet I have put the two magnets together to make up one very strong magnet. and I also used a heavy duty duct tape and covered the dual magnets as they will have over 200 lbs of force so you have to be very careful as it will not be easy to remove off a metal surface or refrigerator. The Duct Tape helps to make the magnets a little less fragile. I helps greatly but you need to still be very careful and learn how to handle very strong magnets so they do not leap or another magnet or METAL SURFACE. Not sure why yet but it seems like all magnet larger than this size will not be a PRIME item? Just something I noticed.
