Purchased new last December, assembled once and then left untouched by an elementary school student. There is no damage, but there are scratches, dirt, and dust. It has been completely disassembled and placed in zipper bags, with the parts list checked. No blocks are missing. Extra blocks are also included. I will not be able to respond if you say "I'm missing the xxx block" after the transaction. This is a layman's inspection, so I may have overlooked something, but please forgive me in that case. Overall, please consider purchasing this as a used item. There is no smoking or pets in the environment. Please refrain from price negotiations.
