Genuine BMW "is" emblem to replace your missing or faded original emblem. This small ‘is’ badge has a self-adhesive (peel off) backing. Simply clean the area of your trunk thoroughly, line up, and stick this “is” badge on.
The other number badges are sold separately. This is just the “is” portion, which is normally adhered after either the 325 or 535 emblems.
