Look no further for a dual purpose eyeliner and eyeshadow that is blendable and SMUDGEPROOF. Yes, you heard right. It's smudgeproof. You have approximately 10 seconds to apply and manipulate before it sets and stays ALL NIGHT. If I have time, I usually use an eyelid primer first such as NARS lid primer, Laura Mercier's eye basics or metallic creme shadows and apply it all over the lid. Then I either apply the Caviar Stick Eye Colour directly to my eye and use the Laura Mercier Creme Detail or Smudge Brush to blend and smoke out or you can rub one of the brushes onto the Caviar Stick before applying to the eye. Experiment and see what works best for you. I do either depending on my mood. You can get a more precise application using a brush to apply the product. My favorite and most used colors are Smoke (a gorgeous dark gray) and Plum (a beautiful plum-ish purple). You can even put the Caviar Stick Eye Colour in your waterline and it stays pretty well!
