This is a wonderful ladies' laptop bag!  I returned mine because I thought it too big for my petite size.  Well I have a bag now that is not as big, but it doesn't hold half as much as this one would have.  On the inside it has I believe 3 loops for pens/pencils, about 3-4 slots for ID, credit cards, and/or business cards, fits a laptop of screen size 15.6" perfectly, and I believe it would hold up to the 16" size as well (as stated). I bought the one with a pretty purple liner in it.  It has great padding for laptop, has roome for external mouse, flash drive, mouse pad, a 4port hub, a chill mat, and more.  Could easily fit all of that and files with no problem. The 2 handle straps are sturdy and ajustable by one belt like secure buckle; which was perfect for me to have on the last hole because I am a full time student who carries the laptop bag, a regular purse, and of course my backpack.  I believe I could have used this as an all-in-one bag.  It definitely would have held my essentials from my purse, along with everything I listed before, and my school book and notebook.  It is an amazing bag, don't let the size bother you if you are petite because again this can be used as an all-in-one bag.  Wish I would have kept it =0(.  Also very nice soft leather so flexable to move around, but not so much as to bend files.  It is the perfect ladies' laptop bag, definitely A+++++.
