Using this eye shadow quad plate is a breeze. First, pick your desired color from the four available shades. You can use a small, flat eyeshadow brush to apply a light - colored shadow all over your eyelid as a base. Then, use a darker shade in the crease of your eyelid to add depth. A high - light shade can be applied to the inner corner of your eye or on the brow bone for a brightening effect. When you're done using it, make sure to close the lid tightly to keep the eye shadow fresh. Store it in a cool, dry place away from direct sunlight. Also, don't share your eye shadow with others to avoid the risk of eye infections.
