This is perfect for quick, on-the-go touchups. Personally, I don't carry around a bottle of makeup remover and a bundle of q-tips in a clutch for a night out. Ingenious idea, does its job well.
HOWEVER, I would have preferred these to be individually wrapped, like how toothpicks are wrapped in restaurants. I don't like the idea of carrying around the whole box just to touch up with one q-tip, but letting them roll around in your purse is pretty unsanitary.
