Vintage Metallic Silver Evening Top-Handle Bag

Super cool sleek vintage metallic silver top-handle evening box triangle bag. Smooth pebble finish with a classic clasp closure. Triangle shaped silhouette. Easy ball clasp opening. Interior has some signs of wear (creases and some light stains). No major flaws on the outside beyond obvious signs of wear for its age. The silver hardware is a bit smudgy/could use a polish. Overall amazing condition and bag. Unsure if it’s leather or not.
