The first thing that comes to my mind is a magazine perfume insert. The kind where the page is glued down and you open it and smell a sharp fragrance and paper. The smell is fresh and seems as though it could cover up very common scents. This smell reminds me of whenever I would go out to places at night where people smoke a lot. At home I used to go to a local pool hall which was always filled with smoke and I used this to spray myself when I got home.
