I found a couple of these while helping someone and wanting to see if they are in fact authentic. They are dates on the bottoms ranging from
"March 1, 1988 to March 2 1988". The color and not having a label left is what's really throwing me off. They are a touqoise and dark plum/maroon on the metal. I've reached out to HM directly but haven't herd anything back yet. As of now this is the only picture I have but can provide more to help ID them!
