This is a set of four (4) J G Durand Luminarc / Cristal D’Arques red & clear wine stems. They were produced in France in the 1960’s, and are embossed, “France” on the bottom.
These stems are in excellent condition. When I purchased them they were in the original packaging, so I know they have not been used.
Take a look at the pictures, and if you have questions, please e-mail.
