Most are, due to the limited availability of microwaves in India, although this has changed in urban centers now and I have seen microwave safe plastic ones as well. Generally you (or your chef!) would pack the food hot in these metal containers and then place the entire tiffin inside an insulated vacuum flask like container so that it stays warm till it reaches you. Here's an Indian site that is selling a microwave safe tiffin set with a built in heating mechanism for under $10. I just googled for it, so I can't vouch for the quality though. http://www.rdsons.com/prods/kitchen_apps/elictrik_tiffin.html http://www.rdsons.com/prods/kitchen_apps/elictrik_tiffin.htm...
