This is the tallest tumbler I’ve ever seen at 6.5”, which is 1/2” taller than a pint glass, so it easily holds at least 17 ounces of liquid. I can’t find any exact matches online other than 10 ounce tumblers, which would be a standard size. In terrific condition, this glass by Libbey with the classic Blue Willow motif could easily become your favorite glass. This puppy demands an Arnie Palmer and a summer night out in the yard.
