Briefcase on wheels.  Very durable.  I am a professional.  I have to bring along a laptop, files, pens and other writing implements  and small purse in a briefcase to work everyday.  I am very hard on briefcases.  This one is very durable.  I usually go through  1-2 briefcases every year.  No problems with this bag.  I have been using it for months now and it still looks new.  I get a lot of compliments.  it is waterproof and holds up to being dragged up escalators, stairs, stuffed under chairs. Replaced a Samsonite rolling briefcase that was my go to brand but I wanted a more feminine briefcase. Pockets on side to put newspaper, water bottle, hand sanitizer, umbrella.  There is a strap at the back that allows you to travel with it on a suitcase.  Inner pockets for ID, wallet.  Plus you get a small wristlet that I keep inside the inner pocket.  The designer thought of everything.  Buy it you will have no regrets.
