Michael Kors Hobo Straw Bag with certificate of authenticity

If this purse has been used, I cannot tell. Hardware has no wear and is shiny, straps show no wear , and body and interior have no stains or wear. I found a little thread on bottom (see picture). Straw with black leather handles with gold hardware and key chain attached. Light cream inside. Dimensions: 14 inches wide, 9 inches tall, 5-6 inches across bottom. Handles to bottom 15 inches.
