These static clings are designed to hold to any glass surface without using adhesive. Clings hold just as well from either the front or the back, so they can be mounted on the inside or outside of a window or other glass surface. (Not recommended for the exterior of vehicle windows.)
PLEASE NOTE: This product is available as an add-on if you are also buying one of our other self-fulfilled products (dice, embroidered patch, enamel pin, or beanie). If you plan to add one of those to your cart, use this cling listing instead.
