Matsutoku Glass's "Usuhari" glasses. Two pairs. Size: Diameter 7 x Height 13.5cm x 2 Capacity: 375ml Each one is handmade by skilled craftsmen, achieving an extreme thinness of about 0.9mm, less than half the thickness of ordinary glasses. They are widely used in high-class Japanese restaurants, traditional Japanese restaurants, restaurants, bars, and more. The delicate rim brings out the flavor, and there is a unique taste to the sound of ice and the feel in your hand. Matsutoku Glass, which was founded in 1922 as a production factory for light bulb glass, manufactures these glasses by utilizing the thin-blowing technology cultivated in light bulb manufacturing. The name "Usuhari" (thin glass) was given because the glasses feel less foreign on the lips, allowing you to enjoy your drink even more.
