Nousaku Tumbler 501340 200cc I received this as a gift. I am selling it to organize my dish cabinet. (Nousaku chopstick rests are also on sale) This small, perfectly sized tumbler is made of 100% tin. Perfect for a casual drink every day. It has high thermal conductivity, so putting it in the refrigerator for 1-2 minutes will allow you to enjoy a well-chilled beverage. It is made using tin based on the casting technology cultivated through the processing technology of "casting," which is a traditional industry in Takaoka City, Toyama Prefecture. Since ancient times, it has been said that "water in a tin vessel does not spoil" and "the impurities of alcohol are removed, making it delicious," and it has been used for sake vessels, tea utensils, and the like. Tin has a high ion effect and is said to purify water and mellow beverages. *Please understand that this is a used item stored at home before purchasing.
