Our reed diffusers are hand-poured in small batches. They are a great flame-free option for dispersing aroma into bathrooms, kitchens, small offices, or bedrooms. All reed diffusers contain phthalate-free fragrances. Reed Diffusers are low maintenance, pop the reed inside the glass jar and let it go. Anytime the scent starts to smell faint, turn the reeds upside down and continue to enjoy the fragrance until it evaporates.
