I have pretty much given up hope on the overseas supplier. Today I started looking at local options and to my surprise EVERYONE is out of stock on the 1/2" x 1/2" Neodymium epoxy coated magnets.

I did however find 1/2" x 5/8" epoxy coated magnets but they aren't cheap and if I do get these as replacements I'm not responsible for broken fingers or glass. :0

Chris is this the size your custom corner racks have?
