Junk items. These items include those with discoloration and signs of aging. There is a possibility that pieces may break when connected. Please understand this before purchasing. There are definitely 500 or more pieces (we'll include extra). Colors and types of pieces are random. These are hand-me-downs, gifts, or items purchased at various times, so the condition of the pieces varies. While there are differences in manufacturing batches, all are genuine products. We inspect for dirt and cracks, but there may be some dirt that couldn't be removed, unnoticed scratches, or overlooked dust. Please be aware of this. We are looking for buyers who understand that these are used items that children have played with.
