they are in 2 or 3 pieces. This is ok for the short term and easy to fit but after a while the edges will peel or curl.ÂÂÂ
Raceboy - In the first pic of this post you can see the black vinyl decal fitted around the rear window on the tailgate of my car.This was fitted to all GTi models as far as I know and is OEM. The part is obsolete from VW stock and has been for many years. A lot of cars have lost this either through wear and it being removed or taken off for a rear end repair/respray. Sounds like this might be the case with your car (unless it is not a GTi model.....)Hope this helps
It was just part of the trim when they were made.  Many people prefer the OEM look. If yours is bright yellow you obviously don't. BTW, your car is only a valver if it has 16 of them
