Genuine smart fortwo (451) Brabus thicker line. Vinyl set in matt red door sticker.

There is no glue that you need to add they are sticky vinyl with adhesive just like any other sticker easy to come out if you don't like it in the future you can just peel it off from the door panel that simple. 

I added a YouTube link of how to install the vinyl sticker on a car.
