Gold-band cast glass was a particularly opulent type of early Roman glassware. It combines canes of brightly colored translucent and opaque glass with strips of gold leaf encased between layers of colorless glass. Only a limited number of vessel shapes were made in this way, and some of the most common are small globular or carinated bottles such as these. They were presumably used to store expensive cosmetics and perfumes.
