This is an OGK cycle trailer. I purchased it from the official website. I attached it to a bicycle, but I never used it for long trips. I only used it a few times to carry luggage in my yard at home, and then stored it in the garage. All the parts are included. Since it has been used so few times, I think the condition is not bad, but as it is used outdoors, there may be some dirt. There is no instruction manual. Please check the official website. There is no original box. I will remove the tires and pack it as compactly as possible using materials I have at home. I have a cat, so please refrain from purchasing if you are at all concerned. - Product Name: Camily Cycle Trailer - Price: ¥29,700 (tax included) - Features: Bicycle trailer, for children, ideal for outdoor use
