A reader will find I am a big fan of Clinique products. The Quickliner is a great product. I love the twist up action which prevents the need for sharpening eye pencils and the opposite end with smudge brush is wonderful. Everything you need for a quick and accurate eye liner application in one little product. The Quickliner comes in so many different shades too! I love the forrest green and egg plant colors - they are subtly different than your traditional black or brown but can make different eye colors or eye shadows pop in a different way. Like most Clinique products I've tried this goes a long way! One Quickliner product can last me half a year. Another thing I've been impressed with using this product for a while is that I have never had issues with the eyeliner breaking off. Probably because you can easily control with a twist up or down how much product is sticking out of the end of the pencil.
