I made a mistake due to poor reading comprehension.
I bought a pair of Oppo stickers on Etsy. I got that they were vinyl, but thought that meant they were static cling. They are not, they are decals.
It might have been okay though if they were made to be put on the inside of the car window. Unfortunately I also missed the part that said you could have them reversed to do that if you specified. So double fail on my part
I don’t like stickers on the outside of my car. Oh well.
