Tsugaru Vidro 1-go Sake Bottle, Emerald Green

This is a 1-go sake flask from Tsugaru Vidro, approximately 30 years old.
It's a beautiful glass flask where transparent blue and green blend together to create a sparkling emerald green hue.
As it has been used, there are minor scratches that are barely visible.
Thank you for your understanding.
Alcohol will sparkle in this beautiful emerald green Vidro glass.
