Not sure how specks of what looks like black felt get in and around cut edges of the vinyl, but every set of door cups had it when I received them, some worse than others, but even after trying to pick them out to remove, some still remain and on my silver and white vehicles, they show up on vinyl.
Had 2 separate orders, and both arrived the same way, so thinking it is a flaw in the cutting or shipping process. Also on last order the cuts were not very clean, a few jagged/rough edges. Lastly, the door cups for each vehicle do not look like diagram when ordering, are more oval shaped, but they work.
