Shiny, glossy, glass-like, buffed. Whatever you call it, the 12 ounce Rocks Glass is flawless. With a sturdy, rounded out base and tapered upper walls, this cylindrical design mimics the old fashioned rocks glass but is useful for hot drinks too. The sophistication of this 12 oz Rocks Glass will do right by whiskey, margaritas and wine, as well as tea and coffee. This is an often overlooked size but a legitimate insider favorite.
