These metallic parts should have a soft, brushed finish. Height: approximately 6 inches (15 cm). Capacity: 16 oz (473 ml). Composition: Front view of the tumbler against a pure black background. Dramatic side lighting to emphasize the texture of the pattern and the metallic sheen of the gold accents.
