Thank you for viewing. This is a souvenir from a trip to Venice, Italy, about 25 years ago. It's made of metal. The purchase price is unknown. It's also unknown whether this type of keychain is still sold. It's unused, but the plating is peeling. It's darkened, but I will list it as is without polishing. The mask part is not flat, but bowl-shaped (photo 6). Please be sure to read the profile before purchasing.
