Engraved Rocks Glasses. The popular typewriter font is used to give our custom engraved scotch whiskey glass a timeless retro or vintage appeal. With the current popularity of steampunk design or industrial design, this vintage type font will fit right in on your industrial loft style bar cart. Our master sand carvers will deeply carve the background panel out of the rocks glass so the initial is left raised from the bourbon glass surface. This gift is the one that will make jaws drop! Lead Free Crystal Rocks Glass Option: Want to upgrade your rocks glass quality? Select our Lead Free Crystal glass by Ravenscroft. Measuring 4' high, this quality crystal double old fashioned glass adds weight and style to your whiskey glass with a beautiful bubble feature in the center of the sham. We recommend hand washing your crystal bar glasses.
