Eg-gu brand shoe polish containers made from glass and Bakelite. These are ideal for reenacting and displays since they are virtually identical to war time Eg-gu but newer made (1950s/1960s) so you don't have to feel bad about beating it up a bit.
These are new old stock, still sealed with some black shoe polish inside. It doesn't have any wording about what color is inside, so you could re-fill however you want. Price is for one. They measure about 2 7/8" diameter.
