Yamazaki Jitsugyo Tower Series Lunch Box 750ml This is a one-tier lunch box/food container with a simple design and a gasket, which is uncommon. I've used it 2-3 times and like it, but it's a bit too big, so I'm selling it. As shown in photo 5, there are scratches that look like they were made by chopsticks, but otherwise it's smooth. Photos 6-9 are excerpts from the website. Would be great for those looking for a larger lunch box or food container. If you don't need the protruding part of the outer box for hanging on a hook, I can also ship it via Yu-Packet Plus, so please let me know.
