Thank you for viewing. This is a commemorative item from the "Tokachi Ocean Expo" held in Hiroo, Hokkaido in 1988, 36 years ago. It is a stainless steel mug. New, unused Stainless steel mug It is rare and not often found on the market, making it highly collectible. How about it for expo and retro goods collectors? It has been kept wrapped in paper since the day it was purchased. For those who understand home storage, thank you. #ShowaRetro #Collection #EXPO
