A rocks glass is a 12 oz. heavy duty short tumbler used for serving a drink like whisky with ice cubes (on the rocks) or cocktails like the Old Fashioned. These rocks glasses showcase the best of Derek’s Abstract Fish Flank Series in a beautiful fully wrapped print within the glass that almost has a stained glass like appearance. Available in Rainbow, Brown, Brookie or Cutthroat. Buy as singles or as sets. Great compliment to the Pilsner Glasses. Microwave safe, but not dishwasher recommended. Made in the USA.
