Heh, I remember that. lol
I think I may have found the answer (?) Looking up the UPC, I found an image of that tin, but it's saying it's SMB/Zelda Valentine's Day cards?

Doesn't show the image to dead listings, but Google's image search found the same tin. So it may not be shampoo or pajamas, but cards?
