The Cozy Cotton Car Diffuser adds a fresh smell to a small space. This USA-made diffuser features a miniature glass bottle filled with scented oil with the clean fragrance of cotton blossoms. The bottle has a wooden lid that allows the oil to slowly release the scent. To activate the diffuser, unscrew the top, remove the plastic plug, replace the wooden top and turn the diffuser over so the scented oil can be absorbed into the top. The more oil absorbed, the stronger the scent. Hang this bottle on a rear-view mirror using the string hanger, or place in a locker, bathroom, or other small space to enjoy the light fragrance. Measures 1.75" high by 1.75" wide by 1" deep.
