Tumblers are all unique and hand-blown and so natural variation occurs. The tumblers may not be exactly as they appear in the photo but they will be a cross approximation. Tumblers are sold individually but if you purchase two or more of a style we will try to match them by size to make sets. They average between 5 - 6” tall. Handblown glass in not dishwasher safe and it vulnerable to temperature extremes. Do not use with boiling liquids.
