This is a plastic egg carton from Tienda Inglesa.
We have not bought eggs from Tienda Inglesa in years – five or six at least. I discovered eggs are cheaper in the street market (feria) so bought eggs there, but because the best feria packaging for a dozen tends to be a plastic bag, I started carrying this with me. Now I buy them next door in recycled cardboard trays of 15, and put them in this container for storage (actually, we have two of them).
Five or six years? At least, and quite probably more.
And why the one egg on the lid? Because this single use container, meant to be opened 12 times at the most, has been opened and closed hundreds of times and is still springy enough that without a weight, the lid will pop back over the rest of the eggs.
And most people will simply throw it in the garbage.
