    Giving this a five star review because the order was shipped fast project was as described, however, FedEx didn’t deliver the package until after it circled the south east of the United States for a week past the delivery date. My issue was with FedEx on this, not with the seller as the seller shipped exactly when they said they would. Would do business with again like I said issue was with FedEx not seller
