Good evening, I just noticed one of the wrappers on one of my Blue Blades is different than the others I have. I recieved the blade as part of an auction I won two weeks ago. There were also two Barbasol double edge blades and a blade bank in the auction, (the blade bank was why I bid on it), so anyway I see that the Gillette Blue blade is darker blue , than my others, and the background surrounding King Gillette's image is also blue, instead of white like my other wrappers. The blade is made in USA and the first patent number on the back is 1633739, and a reissue patent number is 17597. I've never seen a wrapper that was all blue like that, can anyone tell me anything about it? Is it worth saving? Thanks everyone.
