Dabbawalla is a delivery service in major Indian cities that brings lunch to the workplace in metal containers. Translated to the semester topic "glass", a modern version of a food transport container has been created.
Three containers, two with 500ml each and one with 1000ml can be stacked above each other. The lids also guide the containers above and close positively with the containers. The lids and containers are held in position by a stainless steel clamp.
