One of the things we like to do while staying here in Saigon, Vietnam is go out for an hour walk around the city, just to see what we can find.
The other day we saw these stacks of box lunches that were being delivered to a construction site! I love these things! They are all stackable and easy to transport.
In another area there was a woman filling up these plastic boxes with food and two construction workers stacking them up to take them off to the other workers.
