I am not much of a fashion minded person and strive for function over style...so I usually purchase the least expensive  Walmart purse I can find that I think will do the job and use it until it falls apart and then buy another one.
The last purse of this kind, my son called "the black abyss".
He is 13 and sits in the passenger seat while I drive; he is home schooled, so we spend a lot of time together, a fair amount of it in the car.  Whenever I need a  comb, or a piece of gum, or my cell phone answered etc etc, he has to dig in my purse and find it because I, of course, am driving.
This was impossible with the "black abyss" which seemed to swallow things whole.  He HATED that purse so, for Christmas, I bought a different one for me, but really for him.
I bought this purse and it is remarkable. Everything I need from lip gloss to epi-pens fits into this little miracle and IT ALL STAYS ORGANIZED. Amazing. I carry it every day, and here it is almost April with still no signs of wear and tear.
I (and my son) highly recommend it!
