This is an Arcopal cup purchased at a European flea market. It's a vintage item, but it's in good condition with little sign of use, and the milk glass still has its luster. I couldn't get a good picture of the stamp, but it says "arcopal FRANCE." If you have the same type, they can be stacked. It wasn't mass-produced like the famous Lotus series, so it's a rare type. Would anyone looking for one be interested? Diameter: 8cm (cup part) Height: 6cm There are no cracks or chips, but there is some peeling of the print. I hope that those who understand vintage items will purchase it (^^)
