Carbone White Mug Showa Retro This appears to be a novelty cup from the past, possibly from the bone-shaped candy called Carbone. (Perhaps the intention was to drink milk and get calcium...?) I received it as a gift, so I don't know the details. The simple white mug has the word "Carbone" written on it. Please understand that this is a vintage item stored at home, and kindly consider purchasing it if you are okay with its age. Coffee cup Mug Rare item Rare
