She's smiling because it smells good!
Turn your car into a smelly museum with this aromatic masterpiece! The Mona Lisa Air Freshener has a pine scent.
It is 10 cm tall and includes a string for hanging. If Leonardo da Vinci were driving around in a Honda Civic, this is the air freshener he would use to keep it smelling sweet. (He has been dead for a long time, so it would be pretty rank in there.)
