Miyoshi Seisakusho Lunch Box with Integrated Ice Pack - Round This lunch box has an integrated ice pack. It comes with a raised bottom, so it's great for salads and other foods that you don't want to get soggy. Can be used as a single or double-tiered lunch box. You can separate things like salad and spaghetti, and combine the ingredients and pasta right before eating. I'm selling it because I no longer have a use for it.
