This is a protective cover specifically for seat rails. There are four pieces, each approximately 94cm long. The product description states that it fits the Serena C28, Alphard, and Vellfire. I used it on a Serena C27 gasoline car for about a year, so it also fits the C27. Since it was used, there are some scratches, but overall, it's in good condition. It has been cut, so please check the image with the measuring tape. You can use it immediately by simply inserting it into the rail. No adhesive tape is needed, so it's easy to remove! It's designed to prevent gaps and dirt on the seats and is easy to install. It's an item to maintain the aesthetic of your car's interior. Please note that it will be packaged in simple packaging such as vinyl, without using cardboard. Thank you!
