Using these 3D imitation ecological eyebrow stickers is super easy. First, clean and dry your eyebrow area. Then, peel off the sticker from its backing and place it on your eyebrow. Press gently to make sure it sticks well. When you're done using it, you can just peel it off. Remember, since it's waterproof, it may take a bit more effort to remove. You can use a gentle makeup remover. Keep these stickers in a cool and dry place to maintain their stickiness. Don't expose them to direct sunlight or high humidity as it can affect their quality.
