Great suggestion! I just love these! :D
They were a trivia prize, so I don't see why that would happen. It's an individual item, not a line of them like in the main shops.

It's nice to dream though, right? :)
I'd actually really like there to be a few new styles of glasses. I agree very much that some more colours in that particular style would be nice, but having a wider variety of glasses would also be quite nice.
I really like Titania McGee's glasses, but those are an NPC base and aren't available.
