Please ensure that the air freshener is fitted freely so the freshener has room all around for air to circulate and that is does not come into contact with anything surrounding the rose. The air freshener is only to be placed on the air vent of your vehicle. Please check your air vent allows clips to be added as these may not be suitable for all vehicles. We recommend checking the area after fitting to ensure it is fitted correctly and air can circulate around the rose. If you have opted for a fragranced rose or fragrancing at home please ensure the oil is fully absorbed into the procelain prior to attaching as some oils can be corosive to plastics. These air fresheners will only work on an air vent as the air needs to be circulated. Please do not attach these to any other parts of your vehicle or place near any materials.
