Silver metal lunch box, rectangular shape, medium size. A Showa-retro lunch box and side dish container. I found it while cleaning out my grandmother's house, who was born in the Taisho era. I washed and disinfected it. It may not be usable, but I'm listing it in case someone needs it. It is stamped with "[Ouchi Kyosui]". If you'd like it, I'd like to give it to someone. Large one: 17 x 11 x 4.5 cm Small one: 13 x 9 x 3.5 cm #ShowaRetro #LunchBox #Antique
