I imported from Japan. The most popular "Usuhari" is made by skilled craftsmen of Matsutoku Glass in Sumida-ku, Tokyo. The glass made with the technology to make a light bulb is a masterpiece that conveys the spirit of the craftsman and the uniform thinness that is never possible with a machine. Because the area of the thin glass is small on the lips, it is an inspiring glass that conveys the feeling that the ice melts and turns around while drawing out the original taste of the drink. It is a set product that is perfect for gifts for those who like sake that has been created in order to enjoy high-quality cold sake. Sake pouring is a gem that only limited craftsmen can blow from among Matsutoku Glass. In order to blow up to this sophisticated shape, highly difficult technology and years of experience are required.
