Bill,<br>Yes I have seen those. In fact, I have one of the three level carriers. It's a good container for picnics but these are neither air tight nor water tight. They are also heavier than the more popular tupperware containers. But the plus side is that you could rewarm food over an open fire/grill with these. :-)<br>They are pretty common out here in Asia and are commonly called 'Tinkat' (Malay, I think).<br><br>Lots of Singaporean families are too busy to cook and are too tired to eat out all the time, so some catering companies have this 'Tinkat Dinner' service where rice / one veg dish/ one meat dish and one soup are delivered to the doorstep in these food containers.<br>All in all pretty useful. Your local asian supermarket may sell these though. But if you can't locate these, I'll be more than glad to send one out for you...<br><br>
