These vampire lips earrings are available in three sizes: large, which is attached to a hoop; medium, which is attached to a hook; and a stud size. Should you wish to change the earring attachment to a ball post, hook, hoop, or huggies, please kindly inform me by sending a message during checkout. Otherwise, they will be sent with the posts as shown in the picture. All posts are made of stainless steel. The stud posts are sealed with UV resin. If you have an allergy to cured UV resin, please let me know, and I can embed the post with clay instead.
