Did you mess up your first fang mold? Or do you want to change the placement? Scarecrow Deluxe Custom Fit Fangs come with enough customizing material inside each kit for several applications in the event you want to fit one or both fangs better when you are first customizing them, but, once you're done, your fangs are completely reusable without any additional adhesives. This customizing kit is designed for the Deluxe Vampire Fangs (Classic and Small) by Scarecrow. Please be aware that the Deluxe Fangs already include a customizing kit to fit your fangs. Not for use with the retractable fangs as the molding kit is different.
