Mine arrived in a tube rolled up............no wrinkles...........however when I put mine on, had everything lined up, I started at the top first..........a little mistake in that the water softened the paper toward the center and it got soft so when I had the top secure and pulled the bottom up to put it down and pulled the paper off, there was some particals left on the upper part......at the middle. I was successful in getting them off before finally securing the bottom.......all turned out well.
Good Luck.
