My purse is actually a small camera bag. I downsized in hopes that I'd stop carrying so much stuff, but I might have to trade up again. I'm going to try an item I found on Amazon, hopefully it will fit!
I'm a graphics artist and photographer so I've got a plethora of camera cases. The ones for my DSLRs have movable Velcro compartments for arranging your lenses, I keep a small section closed off for my Provari or other mods if I'm taking one of them.
The Provape site has a rather small one with a hard outer shell and foam insides that I want to say is actually made by Cigar Caddy.
There are a TON of really nice hard shell with foam inner padding carrying cases on Amazon. Try searching for insulin kits or insulin carry case, etc.. Since they're designed to carry the insulin and needles for diabetics, they work really well to protect your device and come in an array of different sizes.
This could have changed since I last shopped around online vape shops close to two years ago, but be leery of some things marked as mod cases.
I paid for three cases in particular that we're NOT originally designed for mods, and turned out to be very poor cases for them as well. One, believe it or not was a waterproof sunglasses case. One was a Sony PSP case and another turned out to be a Nintendo FS case..lol
