This is a glass decanter by Libbey.
It is clear glass in an American brilliant starburst pattern with the #45 near the top. This item does not have the stopper with it. It does say Libbey on the top of the handle but we could not get a clear image.
This item measures 3.5" in diameter at the base and stands 5.5" tall.
There are no chips or cracks on this glass item and it comes in a great pre-owned condition.
