The vases have a double spherical body whose lower part carries pincered decorations, an octagonal flared neck, and a round foot surmounted by a medium faceted knop. Each vase has three spouts and two handles with crests. The handles are adorned with applied flowers in blue, white, and azure glass. The flowers were produced by lampworking, a technique in which Niccolò di Vincenzo Landi was an expert.
