I've got something like that. Two somethings, really. They're not waterproof, and they are sold as purse/bag organizers. I have a small one, which contains wallet, phone, chapstick, emergency cash, lipstick, pack of tissues, Advil, Lactaid, two pens, and a couple other things, and a large one, which contains diaper bag stuff. I put both of those into any tote bag or messenger bag and have an instant diaper bag; I put the small one into any purse and can be assured my purse now contains all the, well, necessaries.
