This set has never been completely opened or used, but box does show some wear (see photos)

The top flap is partially opened. The flap is typically seal on 3 sides (the 2 shorter ends and the long side), the long side is unsealed, but the 2 small ends are still sealed. It does allow me to barely show the contents, which are still in original bags. 

The bottom of the box (still sealed) seems to have had a small amount of water near the edges (shown in photos)
