When you pour sake into the glass, the fresh green leaves of a maple leaf spread out inside? When you pour sake into the glass, the pattern engraved on the bottom of the glass is reflected on the side, creating the illusion of fresh green maple leaves spreading out. This is a unique sake cup made with sandblasted glass! (*Product size: Diameter approx. 7cm, Height approx. 6cm, Product weight 128g, Capacity approx. 115ml) "GLASS-LAB" (Koto Brand Certified) The brand was born from the challenge of three generations of craftsmen in downtown Tokyo, with the aim of "stirring the hearts" of those who receive their gifts. Operating a glass processing business in Kiyosumi-Shirakawa for three generations since 1950, they specialize in flat-cut glass, a technique currently practiced by only about 10 technicians in Japan. They have combined Edo-style cut glass techniques with world-class sandblasting technology capable of drawing lines as fine as 0.09 mm, developing their unique "sand-cut glass" technique. Beyond domestic exhibitions, they have showcased their unique technology globally, including at the Milan Salone in Italy, and are a noteworthy brand featured in various media. "Sand-cut glass" (Sand-cut glass: Trademark Registration Number 6193156) – glasses that stir the hearts of those who hold them. In Koto Ward, companies that manufacture products using superior technology and strive to pass on and develop that technology are certified as "Koto Brand" companies. GLASS-LAB is a certified "Koto Brand" company. When alcohol is poured into the glass, the pattern on the bottom of the glass reflects onto the flat-cut side, making it appear to spread out. It is a beautiful glass to look at, a delight to pour, and a joy to drink from, providing enjoyment to the drinker through its use. "Sand-cut glass," a combination of "flat-cut glass" and "sandblasting" (sand is released with compressed air to create engraving), creates a completely new Edo Kiriko. It uses a double-layered overlay glass with a light blue base and a vibrant emerald green overlay, expressing the image of fresh green maple leaves reflected on the water's surface. It uses custom-made "colored overlay glass," which is commonly in Edo Kiriko. This glass product is not made of heat-resistant or tempered glass. Incorrect use may cause scratches and breakage, so please observe the following precautions for safe use. Wash before use. Wash with a mild kitchen detergent and a soft material such as a sponge.

Do not pour boiling water into it as it may break. Do not put it in the freezer. Do not put metal products (spoons, knives, forks, stirrers, etc.) inside the glass or use them for storage.
