This is a Shinkalion the Movie: The Drama CD lunch box. If I recall correctly, it's a rare Evangelion type, with a streamlined navy train and red lines as its features. I'm not entirely sure, but it's definitely a Shinkalion lunch box. This is the container from a bento box purchased at a station kiosk. After finishing the meal, it was washed and used once as a lunch box, and they seemed very happy. It can also be used as a small item container. Size: 23.5 x 6 x 6.5 cm Please read my profile.
