A hallmark of the SGHR Sugahara workshop, the Duo Collection blends a stately, modern silhouette with a mesmerizing optical illusion. By fusing two layers of glass, master artisans create a permanent horizon line that makes the vessel appear perpetually filled. This sophisticated design features a luxurious heft and a delicate interior curve inspired by the elegant fold of a kimono collar, making it a handcrafted masterpiece and the ultimate vessel for your favorite spirits.

Handcrafted by Sugahara artisans. Due to the nature of handmade glass, slight variations and natural inclusions may occur, making every piece uniquely yours.
