Car Freshies are made with premium oils and premium heat activated scent releasing beads that are then made into different shapes and decorated. Car freshies come packaged in polypropylene scent proof bags to ensure the longevity of fragrance. Car Freshies can last 3-6 weeks, depending on scent potency and environmental temperatures. Please note one can become “nose blind” to scents even though the car freshies is still fragrant. It is recommended to hang freshie after opening on a rear view mirror, locker, or other small space. Do not place freshie on any surface to prevent the possibility of oil staining or freshie melting to the surface. Car freshies are a fun way to bring your personality to your car or small space with the added bonus of smelling good.
