Multi Color / Kate Spade Crossbody or Shoulder Bag

Bag is in excellent condition except for 4 little spots on the back. I have no clue what it is. I included a photo a to show. Bag measures 5” tall, 7.5” long and 1” wide. It has a 21.5” drop. It will hold my 6 Plus iPhone. Has a snap closure and inside pocket. It comes from a smoke free home.
