The refill uses high-quality, skin-friendly fragrance oils and a durable plastic housing. The oils are non-toxic and safe for use in vehicles, and the plastic is designed to withstand temperature changes without leaking or cracking.

Each 4ml refill lasts approximately 3-4 weeks with regular use. The size is compact and fits most standard car air vents. If you need a longer-lasting option, consider purchasing multiple refills or contact us for bulk pricing.

We offer worldwide shipping. For wholesale orders, delivery time depends on your location and order volume. Typically, it takes 7-15 business days for international shipping. Contact our customer service for exact shipping quotes and tracking information.
