Can be used as hat stands or vases, but they are really designed to support a shelf in a store.

Height: 11 3/4"

Diameter of Base end: 4 1/2"

Diameter of Open end: 5 3/16"

There is a small chip on the base of one, and an even smaller flea bite on another.  There are scratches on the feet of the bases from years of use, and a bit of cloudiness in some of the glass.  None of this detracts from the beauty of these pieces when in use.  The design is not exactly the same on each as the twist varies slightly, but the height allows them to be used together.  I have used these three to support a glass shelf for several years.
