The age-old steel lunch box design is back in its newest avatar. The outer body is made of ABS plastic (non-toxic and BPA free) and has a detachable 304 stainless steel tray inside. It also comes with a chutney container. This bento is microwave and dishwasher safe and is easy to clean. The 2-side clip locking system adds to the beauty of the lunch box and makes it leak proof as well. Ideal size to be carried in your school bag or purse or office bag. Because of the outer plastic body, carrying hot food is also easier.
