This is a set of six cut-crystal champagne flutes by Nachtmann, the highly-regarded Bavarian maker of crystal glassware.
They're decorated with a pattern of long cuts and are tall, slender and elegant.
The stems are faceted and shaped with a single knop. They're balanced and easy to hold.
These are second-hand but are unused, in their original box and complete with Nachtmann's labels.
