Junk items. Items may show signs of aging, such as discoloration or blackening. Pieces may break when connected, or may break or chip during shipping. Please understand this before purchasing. There are definitely 500 or more pieces included (I'm including extra). A bonus large tire will be included while supplies last. The large tire is also a junk item. It rattles a lot, but it works. Colors and piece types are random. These are hand-me-downs, gifts, or items purchased at various times, so the condition of the pieces varies. There are differences in manufacturing lots, but all are genuine products. The stamps on the back of the pieces also differ depending on the manufacturing date. We inspect for dirt and cracks, but there may be dirt that couldn't be removed, unnoticed scratches, or overlooked dust. Please be aware of this. We hope that you understand that these are used items that children have played with. We look forward to your purchase.
