This is a set of 4 beautiful light blue stemmed glasses found in Duz detergent in the 1960s! Such a cool conversation piece but also gorgeous and functional. These four glasses are in excellent condition with no chips or cracks that I can find. The Star Sapphire glasses (these are the brighter blue glasses on the right side of the first photo) measure approx. 7 inches tall. The Blue Swirl (which are the darker blue on the left side of the first photo) are approx. 6.5 inches tall. These were all made by Libbey for the Duz detergent company to be given away in the detergent in the 60s. Please see all photos.
