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