What are these A groundbreaking cosmetic tool to help all makeup enthusiasts create the perfect cut crease. Each Crease Line Kit comes with three sets of custom and reusable silicone crease shapes for every eye shape and eyeshadow style. We want all beauty lovers, of any skill level, to be able to skip intimidating techniques for developing the perfect cut crease and get a professional look every time, in a minute. How To Use Step 1: Choose the desired crease shape, then pick the appropriate side for the right or left eye. Insert the spacer into the handle. Step 2: Hold the Crease Piece gently against the designated eye, placing it on the crease. Start with the darkest color in your palette and apply it over the edge of the Crease Piece, as desired. Pro tip: Use a thin brush during this step to help achieve a defined look. Then your eyeshadows should gradually get lighter and your brushes should gradually get larger and fluffier as you blend. Step 3: Once you are finished creating the crease, remove the Crease Piece to reveal the coveted cut crease. Once the crease is done, add color to the eyelid. Pro tip: a lighter color on the lid will help the crease pop and create a sharp contrast. This Kit Includes: Handle*1 Round Crease Set*1 Almond Crease Set*1 Wing Crease Set*1
