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 unclear if this type of keychain is still sold. Although it's unused, the plating has peeled off. It's darkened, but I will sell 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.
