Junk items. Includes items with signs of aging such as discoloration and blackening. Pieces may break when connected, or may break or chip during shipping. Please understand this before purchasing. You are guaranteed to receive over 500 pieces (we'll include extra). Large tires are included as a bonus, while supplies last. The large tires are also junk items. They rattle, but they work. Colors and types of pieces are random. These are second-hand items, gifts, and items purchased at various times, so the condition of the pieces varies. Although there are differences in manufacturing lots, all are 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 hope that those who understand that these are used items that children have played with will purchase them.
