Natural aroma meets modern design. This wooden car diffuser cap replaces standard caps on essential oil or perfume bottles, allowing fragrance to naturally absorb and diffuse through the porous wood surface. Simply attach to any compatible bottle, place in a cup holder or air vent, and enjoy subtle, long-lasting scent without batteries or heat. Made from sustainable beech, bamboo, or walnut wood — eco-friendly, reusable, and effortlessly stylish.
