How to use: Remove the Scent Disk™ from the sachet. Place it into the Car Diffuser (Sold Seperately) by gently pulling the backing off from the metal faceplate. Gently place the backing on the metal faceplate ensuring the longer clip is at the top and click to close, then slide the diffuser onto the car air vent to work its magic. You’re in the driver’s seat, so increase the fragrance strength by turning the body of the diffuser clockwise and decrease it by turning anti-clockwise. Replace your Scent Disk™ every 30 days to refresh your fragrance or to increase its strength. Replacement disks are sold separately. Recycling Tip: Place your used paper Scent Disk™ back into this carton or an alternative paper container before recycling.
