The titanium double-wall vacuum cup is made entirely of two thin titanium plates, creating a durable double structure. The space between the plates gives excellent thermal insulation. Since the natural heat of a hand is not transmitted to the drink, ice hardly melts in a cold drink, and a hot drink doesn’t cool down. There is almost no condensation produced when ice is placed in the cup. And perhaps most importantly, the taste of a drink is not changed. This high quality titanium double-wall vacuum cup is manufactured in Tsubame city in Nigata prefecture, Japan, where is a well known city for metal working. The metal products made in Tsubame are world famous and attract the attention of buyers all over the world. The metal industry in Tsubame was started in the early Edo period by farmers making iron nails in the off season. Gradually the farmers began to make utensils and other products for home use, eventually earning fame for their artistry. Tsubame has a metal working history of 350 years, and the metal workers in this region are known to take great pride in the craftsmanship of their wares.
