This vintage Cut Design Art Glass stopper is a hand-blown piece from an unknown maker. This clear glass stopper is 4.66" long and features a traditional form. It is in great condition. I have used a micrometer to measure the very bottom of the stopper and it measures .88" and the top of the base (it tapers) section measures 1.07". I will note some a small flake on the bottom. Minor but worth mentioning. Please see my pics and please contact me with any questions. I will respond promptly. Thanks for looking.
