amber diffuser

Car hangers use a wooden diffuser cap you invert to absorb the oil, then hang in the vehicle. Listings indicate the scent can last up to around 60 days (about 2 months).

One listing recommends flipping the reed sticks about once a week to keep the fragrance flowing; flip them more often if you want a stronger scent.

Reed diffusers are shown to last about 2 to 3 months, while hanging/car amber diffusers are described as lasting up to about 60 days (around 2 months).

Reed diffuser kits include a glass bottle of fragranced oil and reed sticks; exact stick counts vary across listings.

Amber diffusers are presented as creating a calming, relaxing mood; depending on the blend, they can also provide an uplifting, refreshing, or luxurious ambiance.
