Yep they are just fancy stickers. There is a metal outer and they have a plastic backing which just glues onto the car. I managed to pull the metal off the plastic

Ohhh you got some. Are they facelift ones or pre facelift? If they are pre-facelift i'm very interested I have the fcelift ones and they only just cover the hole. Facelift cars don't have the hole for the indicator so got smaller badges.
