Wine bottle stoppers are made from a variety of woods. Popular woods include canarywood, che-chen, rosewood, olivewood and maple Burl. Close-up images of the woods are available upon request. Size is approximately 1-1/4" diameter by 3 " long. About two inches protrude above the bottle top. A removable silicone sleeve is assembled over a maple dowel. This provides a superior seal compared to cork or "O" ring stoppers, will allow the bottle to be laid on its side and, also allows for cleaning of the sleeve. Size: 1-1/4" dia. x 3" long
