I originally bought these magnets 3 years ago and for a different project have since bought more. Since then we bought a LG fridge with a stainless steel covering that wont take a magnet. There is however on place on the fridge that will, above the Ice maker as there is normal steel behind the skin. I had to add some hardware to the the magnet to make them useful. Every visitor who has seen them, loved them. I got a call to make some additional magnets for a friends, then asked if I would make more for gifts. Looks like this started a cottage industry. Try to sell them on Ebay now.
shipped as said it would should do exactly as I need
for such a small item a lot of shipping I think for only a $1.18 item that weighs almost nothing
These magnets were paired with another of the opposite polarity and the pair formed a sandwich on a 2" X 45" Velcro strip for use as a belt. Six pairs of these magnets are spaced 1.5" apart and held on to the belt with plastic screws and nuts. The screw heads and nuts fit within the countersunk part of the magnets. The belt is worn under clothing to relieve back pain. Overlapping Velcro forms a good fastener to hold the belt around the waste.
