What Does "NOS" Mean?
"New old stock."
In the context of item condition, "NOS" means "new old stock". The item is in new condition but no longer actively produced by the manufacturer. Packaging may also show accumulated dust and dirt due to the extended amount of time spent sitting unsold on the shelf/in storage.
