This is a marble run that allows you to create various courses with 388 pieces. It comes with instructions for sample coasters and a navigation sheet, but I think it's also a good idea to try building freely with a small number of pieces. - Model Name: #Korokoro Kororin Marble Slider - Number of Pieces: 388 pieces - Features: Can create various courses Thank you for viewing. The cardboard box has a few tears. The navigation sheet has yellowing and stains. The blocks themselves are clean as they haven't been used much. I haven't counted them, but I believe everything is complete. [Retail Price] ¥2800 #EducationalToy #MarbleSlider #MarbleRun #MarbleCoaster #Blocks #AssemblyPlay #PitagoSwitch
