When a customer orders a drink on the rocks, be sure to have plenty of the 12 oz Rocks Glass (PLTHRG212C) on hand. This glass with a starburst base is an elegant addition to any bar, restaurant, or catering company. Made of polycarbonate, the thicker base keeps the glass upright despite small bumps along the way. The clear surface ensures that everyone can see exactly what’s inside the glass. To conserve on storage space, these glasses can be stacked one on top of another.
