This 4-piece set of antique tumblers are antique and preloved. Each glass has straw marks, air bubbles, or both. They appear to look like cracks but are not, just straw marks. This occurs during the cooling down process of the glass. A picture has been taken to each glass to show condition/mark. Lastly, one tumbler was used more than the others and has significant upper light blue fading in color. Please zoom in on the photos to see all its details, measurements and condition. Photos are also a part of the description as well. Thank you for taking the time to consider this beautiful collectible set!
