This lovely vintage glass bottle stopper was found at an estate sale. It is made of clear glass. The top has a round ball bulbous shape. The stopper measures approximately 2.33" high x 1.40" in diameter. The plunger measures approximately 1" in diameter. There are no markings to indicate a brand. The stopper has a few light scratches, but is in good vintage condition. It would make a great addition to your collection.
