Car Air Freshener Manufacturer in China
Vent clip, hanging card, organic, spray, gel, and membrane formats — engineered for heat-cycle stability and shelf life.

Built for the cabin environment
Car interiors stress fragrance in ways the home doesn't — daily heat cycling, UV, vibration, and rapid airflow through HVAC vents. Ocean Star's car air-freshener line is engineered around those conditions so the scent profile stays consistent from first use to last.
