Consider yourself warned: once you have one, you'll want them all. That's the beauty of Nail Pak, a revolutionary new nail polish that includes a nail file and 40 pre-soaked, non-acetone remover pads right beneath the polish bottle itself. Everything about this little nail system is chic, from the round, polka-dotted file to the selection of colors, which range from bright pink to uplifting yellow to dramatic plum. There's something for everyone in the mix - and, really, who can resist the allure and convenience of an on-the-go manicure system? $20 at dualitycosmetics.com
