Inspired by European bistro coffee cups, our double-walled Bistro Collection has a visual delicacy that's functional, too. The glass-in-a-glass design creates a layer of insulation that keeps chilled drinks cold and hot drinks hot. Ribbed detailing on the exterior makes the cups easy to hold, and the thin, single-walled rim ensures smooth sipping.
