This is a set of Libbey Crystal Pink drape optic or swag pattern rocks tumblers. Each is 2 3/4" wide and 3 1/4" tall. They are in excellent condition with no chips or cracks. They are not marked, but this is a Libbey pattern. Libbey was rather inconsistent with marking their pieces. The pattern features a three part drape or swag pressed in the glass on each side. Please see my other items for more in this pattern.
