Maison Berger car diffuser set with an elegant lips design, with two separate new in box diffusers and an original fabric Maison Berger gift bag. Never opened and perfect for upgrading the fir tree car deodorizer hanging from the rear view mirror. Maison Berger car diffusers are highly rated for their elegant design, durable metal construction, and sophisticated, non-overpowering scents that last 4-6 weeks. They feature a, ceramic, leak-free system that attaches to vent flaps, offering a luxurious alternative to traditional air fresheners. While most users find them effective at eliminating odors, some note that scent strength can vary based on airflow.
