Looks like a jar belonging to those "Brush/Mirror/Comb/Jar(s)" vanity sets from the 1940's-50's. I believe they were intended for anything that you wanted to put in them, from bobby pins to creams.
I can remember the drug store in our little town about this time of the year. They would have a table display of vanity sets and other gifts, just waiting for us kids who were desperate to find a Christmas present for Mom.
