EkiBen : (Eki = station, Obento = meal in box)
Real Ekiben in Japan is in Foam box (a good quality) cover with Paper Toplid. It was in shrink wrap for cleanliness with chopstick inside. When I bough it, shopkeeper also gave me a wipe (with the commercial tea brand).
In the picture : two Ekiben and Hot Tea (Shizuoka Tea 290g) in can. It was a warm tea labelling with somekind of foamy paper (to protect consumer when handle) --- Very thoughtful, Japanese !!!
