Used a few times as I didn't get into it much. One of the 25 screw parts is missing. It doesn't affect play, and the pull-back motor car that can be made with this kit uses 30 out of 67 pieces, and 5-12 screw parts are needed to build it! There is no outer box, everything is in the images. The instruction manual is badly deteriorated, but it only has the completed illustration and the total number of pieces; there are no instructions on how to build it to begin with. I think it's okay without it, but I'll include it just in case. Target age: 3 years and up Amazon reference price: 5,500 yen
