These devices, often suspended from a vehicle’s rearview mirror, release fragrance into the car’s interior. They consist of a porous material saturated with scented oil, which slowly evaporates, providing a sustained aroma. A common example includes a small, decorative bottle filled with fragrance, connected to a string for hanging.
The significance of such an item lies in its ability to enhance the in-vehicle environment, masking undesirable odors and contributing to a more pleasant driving experience. Historically, these products have evolved from simple cardboard cutouts sprayed with perfume to more sophisticated designs incorporating advanced diffusion technologies, reflecting a growing demand for personalized and comfortable automotive interiors.
