This luxurious car freshener features lava stones strung on a sleek leather cord, designed to hang from your rearview mirror. The adjustable cord allows for a perfect fit in any vehicle. Each piece is "blinged out" with stylish accents, adding a touch of sparkle and personality to your car interior. The lava stones act as natural diffusers, soaking in the included 1-ounce fragrance of your choice and slowly releasing the scent over time. Simply add the fragrance to the stones for a long-lasting, elegant way to keep your car smelling fresh.
