Recursive spice container

I needed to buy saffron and just couldn’t resist this package. It looks like something that the Japanese would do. I wonder if the case that these jars ship in is itself a glass container?

From a lighting standpoint, two big lights to either side and a reflector in the rear was not enough. The camera mounted flash could not be pointed at the scene. The reflection would be too bright. So I pointed it away from the camera and used it to control a hand-held slave flash. I should have turned the firing of the master flash off since it created a new shadow (even pointed backwards). But the slave flash relit the shadow.
