This is a set of eight (8), matching, red cut-to-clear, footed tumblers. I do not know the manufacturer, but they are marked with a sticker, “Made In Czechoslovakia”. They have a pretty floral design cut into the glass.
All eight of these tumblers are in excellent, used condition, and are 4-15/16″ tall.
Take a look at the pictures, and if you have questions, please e-mail.
