Anime chain store Animate is offering this official limited edition NERV Taimeshi Bento at a hefty price of 1,300 yen.
Taimeshi is simply rice with minced sea bream, cost around 400 yen. Bento comes with some NERV chopsticks, and yes the bento box is said to be high quality plastic.
Well I guess the bento box would be good for collection purposes.. But for my meal, definitely not enough >_<.
