I purchased this on the release date and took it out of the box, but I haven't set it up and it's unused. Of course, I haven't put it on my head, so there's no deterioration or smell. The outer box has a few scuffs. All accessories are included. I think it's the cleanest item among those listed, excluding unused items. I'd like to sell it by the end of August, so please don't hesitate to make an offer. Feel free to ask any questions.
