This was received as a commemorative gift. The words "commemorative gift" are engraved on the bottom. It's unused and has been kept in its box. I don't have an opportunity to use it, so if anyone is interested, please let me know. The characteristics of Satsuma tinware are as follows: • High thermal conductivity, excellent for cooling and heat retention • Due to its coarse molecules that absorb impurities, it has a water purification effect • It is said to mellow the taste because it has a large ion effect, second only to gold • Known as a lucky item that "doesn't break" and "doesn't rust" Size: Height 9cm, Diameter 6.5cm
