This is a set of the genuine Panasonic Gyutto Crewm child seat and rain cover (not sold separately). The child seat does not come with instructions. All removed parts will be shipped together, so we recommend having them installed at a bicycle shop. The items have been cleaned. There are minor scratches and stains, but they are relatively clean. Please understand that this is based on a casual inspection. The rain cover was purchased for about 13,000 yen and comes with a dedicated storage bag. This is a child seat exclusively for the Gyutto Crewm EX, so please confirm that it is compatible with your bicycle before purchasing. (We are not responsible for any issues such as incompatibility, so please understand.)
