Although the Japanese didn't invent cocktail culture, they have certainly perfected the tools to make an incredible cocktail. This Yarai Mixing Glass is one case in point. Yarai, referring to the cross hatch cut pattern in the glass, is known for its quality, elegance and durability. Crafted out of one piece of seamless, thick, weighted glass, these sturdy mixing glasses allow bartenders to mix two drinks at once and the glass stays cold longer than other mixing glasses. The spout also makes for a clean and easy pour.
