Junk items. Includes items with signs of aging such as discoloration and blackening. There is a possibility of pieces breaking when connected, or breaking or chipping during shipping. Please understand this before purchasing. There are definitely 500 or more pieces included (with extras). Large tire bonus included, while supplies last. The large tires are also junk items. They rattle, but they work. Colors and types of pieces are random. These are hand-me-downs, gifts, and items purchased at various times, so the condition of the pieces varies. There are differences in manufacturing lots, but they are all genuine products. The markings on the back of the pieces also differ depending on the manufacturing period. We inspect for dirt and cracks, but there may be some dirt that couldn't be removed, unnoticed scratches, or overlooked dust. Please understand this. We are looking forward to purchases from those who understand that these are used items that children have played with.
