what are the dimensions? any markings?
One container has a deeper recession of the face than the other.
They are both 5 3/4" tall
They are both 3 1/8" diameter
They are approximately 1" deep
The stem connecting to the container has an either cloth or suede like material as a seal.
No marking of any kind that I can find.
I almost want to say their interior smells similar to brass instrument oil?
Edit: Could just be the brass smell though.
OK, I think I'm on to something. I can "press" the center of the containers, like an oiler, so that's my first suspicion.
Edit: My father suggested it may be powder related as well.
