Using this eye shadow tray is very easy. First, choose the color you like. Then, use an eye shadow brush to gently pick up the powder and apply it evenly on your eyelids. For a more intense color, you can apply it multiple times. When scrubbing, use a gentle makeup remover. Make sure to keep the tray in a dry and cool place. Avoid exposing it to direct sunlight for a long time. Also, don't let water get into the tray to prevent the eye shadow from clumping. If you have any skin sensitivities, it's a good idea to do a patch test first.
