The vinyls came as a rectangular sheet with instructions. You basically stretch the vinyl over the emblem and then cut it out with a razor blade. The whole process took me about an hour and a half. I ordered "2" and they came 2/sheet, so I got 4 vinyls all together. Turned out to be a good thing 'cause I messed up the first one and had to redo it.
I don't know how long they will last... but they seem to be sticking very well so far. Only time will tell! At least they weren't expensive.
