Some years ago I purchased some very similar looking blanks off eBay, I think. They were the blue ones and I got them because I like to have triplicates of keys for each vehicle...don't ask

. Anyway, these eBay blanks that came out of china were made out of cheddar cheese. They're okay for an urgent situation but not good enough for daily use...in my opinion. I hope yours are made from real stainless steel and not soft aluminum/cheese like mine, however mine do taste good on a cracker!
