Thank you for viewing. This is a Quadrilla Basic Set + Extension Set, a set of two items. I purchased them at Bornelund in a department store in Tokyo. The original price for the two sets was about 20,000 yen. I played with them about three times, and then stored them in a closet at home. Although the specifications are different from the current products, there is an instruction manual, so I think you can enjoy playing with them. All the parts are included. There are only 28 marbles, although there should be 50 originally. (I will add more if I find them before shipping, but there is a possibility that I won't find them.) There are small scratches and stains, but there are no major problems, and they are in good condition. The storage box has some scratches and stains. According to the Bornelund website, Quadrilla is ranked number one and two in the popularity ranking for 5-year-olds, so I recommend it! ☆ You can assemble it with excitement with your child, and not only children but also adults can enjoy it! You will be healed by the sound of the marbles rolling. How about it for winter vacation, Christmas, and the New Year holidays for playing at home? Please understand that these are used items, that they have been inspected by an amateur, and that they have been stored at home. If you are nervous or critical of the condition of the product, please refrain from purchasing as it may cause trouble. I plan to pack the two items together in one package and ship them with a plastic bag on the outside of the box. #WoodenToys #EducationalToys #Bornelund #WoodenToys #Christmas #Present
