With classic yet stately silhouettes, luxurious heft and texture and the unique colors, this handcrafted Duo collection has been one of the best-selling collections of Sghr Sugahara. Their master artisans developed a two layer of glass of differing thickness, that are blended with the fusion line that is perfectly sealed, which makes the glass look like it has water in it even when empty. While keeping a modern look with a sharp straight line, they made the fusing line curved and even added a dimple that looks like a collar of kimono. Vases are also available from this collection. All of our glassware is individually mouth-blown and hand-finished, so item sizes may differ slightly from product to product. The items may have small bubbles or striae (lines) because of natural sand material.
