Mac's Penultimate Liner doesn't smudge easily or wear off like other liquid eyeliners. It is easy to apply and always looks fantastic. Best liner for doing a cat eye or winged eyeliner.
I love the look of a liquid liner, but not all are easy to work with; however, this liner is AMAZING as far as application goes! If you have a hard time getting liquid liner to look perfect, this is the liner for you. The only reason I gave it a 4 star instead of 5 is because I prefer my eyeliner (when in black) to be super dark. It's not bad, but I usually go over it with a pencil or gel liner to enhance the pigmentation.
This is the best eye liner I have ever bought. It is so easy to put on and is easy to build. Perfect for the work day or a night out. It stays on all day, no smudges. BUY!!
