I still have two of the old metal ones taped to my Canon AE-1 camera strap. Oops, telling my age.

The aluminum ones, or the older yellow paint?

I saved the metal ones for years - yellow tops and green (Tri-X) tops - as well as plain ones. My wife uses them for seed containers in our little greenhouse. I shot a lot of that stuff in Vietnam, mostly Tri-X and Kodacolor-X.
