William B. Lutz Pittsfield, Massachusetts Clear Plastic Jewelry Display Box

This is a vintage clear plastic round jewelry display box. The top has a little white floral border. There is a piece of fabric that is glued inside. Overall, the piece is in pretty great shape, but I am not sure what it held. On the bottom, there is text that reads: "William B. Lutz Jeweler 48 South Street Pittsfield, Mass." Approximate Diameter: 1.75 in.
