This is a collection of "junk" items. Includes items that are discolored or have deteriorated over time. There is a possibility that pieces may break when connected. Please be aware of this before purchasing. You are guaranteed to receive over 500 pieces (we'll include extra). Colors and types of pieces are random. These are items that were either hand-me-downs, gifts, or purchased at various times, and the condition of the pieces varies. While there may be differences in manufacturing batches, all are authentic products. We inspect for dirt and cracks, but there may be some dirt that we couldn't remove, unnoticed scratches, or overlooked dust. Please understand this. We hope that you understand that these are used items that children have played with. We appreciate your purchase.
