With classic yet stately silhouettes, luxurious heft and the unique colors, this handcrafted DUO Glass collection is a winning choice for sipping on your favorite spirits. Handcrafted by master artisans, the glasses are developed in two layers of differing thickness that are blended with the fusion line, which makes the glass look like it has water in it even when empty. Design details includes sharp and curved lines and even a dimple dimple that resembles the collar of kimono.
