To use this HERA eyeshadow palette, first, select the color you want. Dip your eyeshadow brush gently into the powder and tap off any excess. Then, apply the color evenly on your eyelid. You can use different colors to create various eye looks, like a natural daytime look or a bold evening look. When you're done, close the palette tightly to keep the eyeshadows fresh. Keep it in a cool, dry place away from direct sunlight. Avoid getting water or other liquids into the palette as it can damage the powder. If you notice any change in texture or smell, it's time to replace it.
