LaQ Basic, 8400 pieces. As shown in the fifth photo, I purchased this myself on Rakuten three years ago for 63,525 yen (including tax). I haven't played with it much, but as you can see in the third photo, there are some slight cracks in the case. There are no breaks. I don't think there are any breaks in the LaQ pieces themselves, but I haven't checked each one individually because there are so many. I haven't confirmed that there are exactly 8400 pieces, but since I've only played with it at home, I think there are very few missing pieces. I confirmed that there are 20 tires, large, medium, and small. I have roughly sorted the colors and disassembled it, but I haven't completely taken it apart. Please understand that this is a used item, including the above condition, and consider purchasing it. Also, I will need to secure packing materials after the purchase is confirmed, so immediate shipping will be difficult. Thank you for your understanding. With this many pieces, I think you can make anything you want! You'll probably have fewer times when you have to give up on a creation because you don't have the parts. Thank you.
