The customer service was not helpful. I previously sent an email asking if I had to buy 8 since they came 4 in a package. I only needed 6. They replied no. I later found out you could buy only six. When I asked if I could return 2 and receive credit, they replied I couldn’t since the skew was different. The covers are very thin. Not what I thought they would be. I’ll keep them but I’m not pleased with their customer service.
