I used these for my lunch, but I no longer need them at work, so I'm selling them. I washed them in the dishwasher and used them for about a year. Microwave safe, oven not allowed. It seems that black is currently not available on the official MUJI website. I am selling them at the price for purchasing everything in the photos. Instant purchase without comments is also welcome. No price reduction. I will delete comments asking for a price reduction.
