Ok, so with the cork in the bottom, this might be a salt shaker..?? But, it's always been used as a hat pin holder.

5" tall, and art deco design

Comes with 3 pins shown here.

The black pin is made of a hard plastic like a button

White pin has a mother of pearl look

The pretty metal pin has a cute filigree design and an old English initial that looks like an F...I think.

Excellent condition..nice!
