This is a 5-7 year outdoor waterproof sticker for your boat. Like Dirty Harry said, do you feel lucky punk? Well do you? They don't know if you do or don't so let them move on to the next boat. A very cheap investment that could save you a lot of money... You will receive two of them... All you do is peel the backing off and stick to a clean surface. They have a clear laminate over them to protect them.
