Enamel pin with Fy'ra from Critical Role. Whoa! Fire for hair! Careful not to singe whatever you pin this to! Just kidding, that's just metal and enamel. It will probably actually feel cold to the touch.
Enamel pin of Dorian from Critical Role. Unfortunately, this pin only displays musical notes and does not play music. You can supply the music, though and tell everyone it's coming from the pin.
Enamel pin of Dariax from Critical Role. This pin won't give you wings, but I'm sure with the right camera work we can make it look like that wing is yours.
