This is a set of working vehicles, a connecting trailer, and various other items. I assembled them for the listing after storing them at home. This is a detailed and fun LEGOSYSIEM series with many small parts and intricate details. The tires move, the doors open and close, the doll's hat can be moved, and the arms can be raised and lowered. The dolls can also sit in the driver's seat and hold tools. As marked in images 10/18 and 11/18, the trailer connects by inserting the connecting part into the hole. *As shown in image 17/18, there is a warp on the right edge, and some have yellow lamps while others do not. The assembly instructions are worn and tattered, so I have marked it as "slightly damaged or dirty," but otherwise, the LEGO blocks themselves do not appear to have any noticeable dirt. Please refrain from purchasing if you are concerned about minor imperfections. If you have any questions, please feel free to ask before purchasing m(_ _)m #LEGO #Blocks #LEGO #EducationalToy BorneLund
