Black composite 4 x 4 post cover

Product was fine, but doesn’t seem it should have taken 2+ weeks to be delivered to the store.

Bad packaging and cheap material

Would Not Recommend

Complete garbage, bought 4 and all 4 had broken caps and some had broken skirts. Packaging is horrible and no cushion to protect during transport. Online was no help in fixing the problem and in store they would only take back the whole set instead of just replacing the parts needed that are sold separately. So I returned all of it and went with a different brand because you can’t trust to get even 1 good one out of 4.
