This is a Tartavin (wine tasting cup) from when I visited Katsunuma Grape Hill in Yamanashi Prefecture. Diameter: Approximately 8.5cm This item was only used once for wine tasting at the facility. A Tartavin is a container used for wine tasting. It has been used in France for a long time, and the unevenness of the vessel is designed to utilize the reflection of light to observe the color of the wine. It has a place to put your finger. The string that I used to hang it around my neck on that day is also included. I will dispose of it if you don't need it. Please purchase this item if you understand that it has been stored at home. #YamanashiPrefecture #Katsunuma #Tartavin
