Libbey Facets drinking glasses plum purple octagonal shape lowballs set of 6

Set of six vintage Libbey glass lowball tumblers, old fashioned rocks glasses 3 1/2" tall (10 ounce size). These are the Facets pattern textured glass with octagonal shape, in the plum purple color! All six glasses are in excellent condition, I don't think these have ever been used.
