Libbey Goblets 4pc

Libbey Duratuff USA Goblets Set of four vintage Libbey goblet style glasses. They are embossed with Duratuff USA on the bottom of each glass. They are a beautiful dusky blue color. The pics show the approximate size as 7" tall, 3 1/2" wide across the top and 3" wide across the bottom. The condition of the set is used. One of them has a slight nick on the bottom. It is not sharp. The last pic in the listing shows the nick. That seems to be the only imperfection on the set. Please feel free to ask questions and reasonable offers are considered. Thanks
