Tiffin carriers or dabbas are a kind of lunch box used widely in Asia and the Caribbean for tiffin meals. From India, they spread to Malaysia and Singapore[1] and Trinidad and Tobago.[2]
In the Indian city of Mumbai, there is a complex and efficient delivery system that regularly delivers hot lunches packed in dabbas to city office workers from their suburban homes or from a caterer. It uses delivery workers known as dabbawalas.[1]
The book Tiffin: An Untold Story covers 172 tiffin carriers, some over a century old.[3][4]
