Moisturizing
This lip balm is really nice. I am constantly buying new lip balm, and this has really impressed me. It keeps your lips very moisturized for quite a long time. I thought it was going to be the size of chap stick, but it’s actually the size of an Elmers glue stick, so it’s well worth the price. I will definitely buy again, if I ever run out 😁
