My little mesh bag of stones and my phone.
On some days, I have a bunch of loose change.
Edit: I guess, I can share what I carry in my purse:
Keys, glasses, sunglasses, glass cleaner, hand sanitizer, gum, mints, lipstick, hair spray (its a spray bottle of water), pencils, pens, a notepad of sticky notes, my wallet, an umbrella, a collapsible mesh bag, a small vial of perfume and deodorant,feminine products, a calculator, a protein granola bar, a piece of dark chocolate, a tire guage, and my mini first-aid kit.
