Using this 16BRAND eyeshadow palette is super easy. First, pick the two shades you want to mix and match. Dip the included mini brush into the eyeshadow, and then gently apply it to your eyelids with a single swipe. For best results, start from the lash line and blend upwards. As for maintenance, keep the palette in a cool and dry place. Make sure to close the lid tightly after use to prevent the eyeshadow from drying out. If there's any excess powder on the brush, tap it off before applying. And don't share your brush with others to avoid cross - contamination.
