What she said. I like car kits because they can carry enough to be useful in any scenario.

I gave up on the pocket size Altoids type kit and decided that my pockets were more suited to minimal EDC user stuff outside a kit. The Altoids kit will be left behind. A serious purse kit would work, but then the purse needs to go everywhere. At least it's useful.

A Continuum of Kits:
Car kit -- big and multiple applications. Available on the road (see Dagny's post)
Desk kit -- not so big but focused on office emergencies.
Purse kit -- smaller, designed to get you back to a serious kit or just to evacuate.
Pocket carry -- User stuff, if you don't at least occasionally see it being useful, it will be left behind.

Note: My EDC backpack functions as my "purse". Lots of good stuff for short term emergencies & egress and it's also a gym bag, but it cannot replace a larger kit such as the 96 hour kit in my truck. Since I have no office per se I skip from Truck Kit to EDC backpack then pocket carry. There's no one size fits all, your daughter needs to commit or all the kits will not help.
