This is a roof carrier from FCS. It goes through the car's interior, allowing for easy removal. I only tried it on once after purchasing it, and it has been stored at home since then. Please check the photos for any scratches on the product due to installation or storage. This is a used item, so please understand that it is non-refundable, non-returnable, and non-cancellable. I will wrap it in bubble wrap, put it in a plastic bag, and attach the shipping label directly to it for simple packaging. Thank you for your understanding.
