Three antique tea trays made of tin. On the back, there is a black stamp with the four kanji characters "三越製" (Mitsukoshi-sei). (I don't know how to read it.) They are soft, so they seem like they would bend if you squeezed them hard with your hands. I don't know the details, so please forgive me. #Retro #MiscellaneousGoods #SmallItems #Objet #Metal
