Using this lipstick is easy. First, make sure your lips are clean and dry. Then, apply the lipstick evenly across your lips. For a more intense color, you can add an extra layer. Remember, since it's waterproof, it might take a bit more effort to remove. Use a good makeup remover to clean your lips thoroughly. Store the lipstick in a cool, dry place away from direct sunlight to keep it in good condition. And don't forget, the minimum order quantity is 60 pieces when you're planning to buy.
