Using these lipsticks is easy. First, prepare your lips by applying a lip balm to keep them moisturized. Then, choose the color you like from the set and apply it directly to your lips. You can use a lip brush for a more precise application. Remember to store the lipsticks in a cool and dry place to maintain their quality. Also, if you have sensitive skin, it's a good idea to do a patch test before using a new color. When not in use, make sure to close the lipstick caps tightly to prevent them from drying out.
