Each Sai glass set from Glass Studio Izumo is carefully hand-blown in Shimane prefecture, a region in Japan known for its deep natural beauty and cultural heritage. The set includes one larger pouring vessel and two rounded cups.
The interior of each piece is finished in jet black, while the outer surface is layered with colored glass over fine silver foil. This creates a shimmering effect, where light shifts across tones of red, green, or blue depending on the variant. The sparkling finish is reminiscent of a starry night sky, making each piece both functional and artistic.
Every set is handmade, so slight variations in color and form reflect the individuality of the craft. The rounded shapes are designed to sit comfortably in the hand, reflecting the studio’s dedication to natural balance and ease of use.
The Sai series embodies Japanese glass artistry at its finest, blending modern design with traditional techniques. These sets are versatile for daily enjoyment, seasonal gatherings, or as meaningful gifts that carry cultural depth.
