Saw this in a Muji Singapore Xmas catalogue. As the bento box alone normally costs S$19, this is a ‘steal’ (though not in Daiso terms!) at S$19 for bento box, lunch bag, and chopsticks with plastic case.
P.S. If you read Chinese, check out the Muji Taiwan site – it’s different from the other regional sites because of the blog-format comments from readers which can be very informative (especially if you can’t figure out what a particular product is for!).
