This is an authentic Crown Royal Block Optic Whiskey Rocks Glass. [1]

Design Features & Specifications

• Brand: Crown Royal (Canadian Whisky)

• Pattern Style: Features a block optic grid pattern (often referred to by collectors as a "windowpane" or "checkered" design). The grid texturing covers the midsection of the glass, leaving a smooth top rim and a heavy, polished clear glass base. 

• Shape: A flared, tapered silhouette that naturally expands wider toward the lip, allowing room for large ice spheres or whiskey stones.

• Logo Graphic: Features the official Crown Royal signature cursive logo silk-screened in a durable crisp white enamel script on the upper front portion. 

• Capacity: Standard 8 oz / 10 oz lowball tumbler, optimized for neat pours, on-the-rocks serves, and classic old-fashioned cocktails.
