Six XXL blown glass stemmed glasses

The glasses are in very good condition, no accidents, no cracks or chips. They are made of blown glass, beautifully made, heavy and opulent. They remained very shiny, and the glass is rich in reflections. What is particularly impressive is their size, they seem giant, and you can see this in the photos where they appear next to the bottle of wine. Their capacity is 500 ml! Each glass weighs around 500g! French regional artisanal manufacturing from the second half of the 20th century.
