I was so excited to get these liners and close the open space in my wheel arches. Unfortunately, I'm happy with it, but disappointed at the same time. You will see in the pictures that the bottom lip is slightly curved (same on both sides) due to the way the item was made/packaged. It looks worse in real life than in the photos but the idea is that they are ugly and flat on the back. At the top, the lid doesn't really fill the gap, but technically it's not visible unless you're looking for itβ¦
