Can be used as a large handbag or small briefcase or both! I bought when I got a new laptop and realized I no longer needed huge briefcase and a purse... used for that one client and then took 2 years off work and forgot I had it! 17" wide at bottom, 15" wide at front pocket. 11" high. 4" deep. Zippers go all the way down at sides so you can easily take laptop in and out. Has front snap exterior pocket, back zipped exterior pocket. Interior has 2 compartments + zipped center section, small zipped pocket, phone pocket, business card pocket, pen holders, clip for keys. Used for such a short time, interior zipper pulls still have plastic on them. I now work from home so I don't take my laptop anywhere.
