When my family and I moved from Córdoba to Madrid it was very difficult to make ends meet since Madrid was much more expensive than Córdoba in every way. 
I had to start working, selling all sellable kinds of stuff: kitchenware, insurance, books, Tupperware sets…
The company would give out “tuppers” to those sellers who met their targets. I still have some around in my house, and this is one of them.
