Furniture Deck

Thank you for looking.
This is a Kaguddekk.
I purchased this a long time ago from someone who said they barely used it, but I have never used it myself and will not be using it in the future, so I am selling it.
It is quite old.
It says S but I'm not sure if that refers to the size. I feel like it might be for petite men or women.
I'm also not sure about the spray size. Please refer to the photos.
I don't know the specifics, so I'm selling it at a low price.
Thank you for your consideration.
