Kokusai Kako Co., Ltd. mellina Butter Case White 194 A series with innovative designs, with the participation of internationally renowned industrial designer Toshiyuki Kita, that popularized melamine tableware in ordinary households. From 1980. 〈Size〉 Approximately 17.4 x 9.8 x 4.3 cm (height) 〈Raw Material Resin〉 Melamine resin 〈Heat Resistance〉 120℃ As shown in the last photo, there are marks from a butter knife on the inside bottom of the main body, but other than that, both the main body and the lid are generally in a clean condition due to the characteristics of the material. No water stains are visible. It has a high design quality and is a sturdy case. I would like to wrap it in cushioning material, put it in a box, and ship it via post. I would appreciate it if you could understand the above.
