Authentic Kate spade navy blue nylon laptop case with shoulder strap. Excellent preowned - one very minor scuff on the back - please see picture for it. There is NO dust bag with this purchase. It does hold my 13 inch laptop and still has a little bit of room - can probably get a 14 inch laptop in but I am not positive since I don’t have one - it’s my guess. Approx. measurements are 15 1/2 x 12 1/2
