I've been using this pencil in combination with the Mac pencil that is not waterproof for the last 10+ years. (Stubborn Brown combined with Coffee) I like to use this waterproof Powerpoint inside my bottom lid because it stays on. I also use it in the corners and inside of my eye too to assure that my liner stays put. I go over it with the regular pencil to get a more defined shape, because the regular pencil has less resistance to it and is more emollient. (if that makes sense) This pencil will stay on forever and I wouldn't be without it!
