Classic sake glasses designed by Sori Yanagi Set of 6 x 2 = 12 glasses Unused Size: Diameter Φ 55mm, Height 65mm Capacity: 60ml Material: Glass Note 1: Not heat-resistant, so please use for cold sake. These are classic Sori Yanagi sake glasses. Referencing the official website: ------------ This sake glass, often seen in izakayas, was designed as a novelty item for Japanese sake. The Japan Sake Brewers Association Central Association requested, "We want a sake glass that can be used for both hot and cold sake, and that has a stem (a foot for holding the glass)." The design process was advanced by the connection between Yanagi, who taught at Kanazawa College of Art, and Hiroshi Fukumitsu, the then-president of Fukumitsuya, a sake brewery in Kanazawa, Ishikawa Prefecture. It took about two years to finalize the design, which resembles a sake cup. The first designed glass (medium) was very well-received, but because the taste and aroma of sake change significantly with temperature, there were opinions that it was a bit too large for hot sake, so a new, smaller size was designed. On the other hand, a slightly larger size, mainly for cold sake, was also considered, but this was discontinued during development. ------------ The box condition is not good. The contents are unused. There may be some dust from storage, but it will not be a problem if washed before use. These are sold for 385 yen each. Buying in bulk is a great deal. Thank you very much! ^_^
