This antique ladies flask is glass that is wrapped in sterling silver in a vine pattern, and has a removable silver cup. The flask measures 4 3/4" tall and 2 3/4" wide and is of the Victorian era. It appears that the glass has been replaced as the sterling wrap is just a little large for it. It is fluid tight, the cap sits tightly and seals over the opening, but we would recommend that this flask be used for decorative purposes only. It is a pretty and dainty piece.
