I understand this is a piece from 19th-century France. They are similar but not a pair. There are differences in size, color, and the presence of air bubbles. Also, one has a distortion at the mouth (see photo 9). Diameter: Approximately 5.5 / 5.3 cm Height: Approximately 17.0 / 16.8 cm Base: Approximately 6.5 / 7.0 cm Returns are not accepted. Please examine the photos carefully before purchasing. The color may differ slightly between the photos and the actual item. Also, there may be scratches and stains due to aging. Please understand.
