Coach cross body bag

Coach crossbody bag with magenta colored lining. Has been used and has signs of wear on the lining near the zipper. Contains two pockets in the bag, one with a zipper one without. Has a sleeve on the outside of the bag on one side. It came with an additional strap but I'm not 100% sure what its function is. The strap is still in the original packaging. The strap is approximately 45" long. Approximate dimensions: 8.5"x6"x2".
