This is a retro thermos (vacuum flask) manufactured in the Showa era by Diya Mahobin Kogyo Co., Ltd. (currently Diya Corporation). It is a product of Diya Mahobin, known under the "Diya-jirushi" or "DIAMOND" brand. The vibrant green body is characteristic, with a retro-pop design that was popular from the 1970s to the 80s. The included box features series names and illustrations such as "COWBOY" and "Little Love," suggesting that it was a model sold for children or leisure use at the time. It has been stored in its original box in an unused condition for a long time. The original box shows damage, and the belt金具 has discoloration, but the main body shows no significant damage. The interior and inner cup, in particular, are in like-new condition.
