X means Kisses and O means Hugs. You can give a Hug and a Kiss all in one small box. Our X and O Earrings are Sterling Silver and are sure to impress. We will ship your Initial Earrings for FREE in a ShameOnJane box or on a Card that expresses how much your friend or loved one means to you. If you choose the card you can write a your own note on the back, or leave it as is. Either way, they are sure to love it!
