Cotton Blossom Car Diffuser is a USA made air freshener with a glass body, scented oil, and a wooden top. Diffuser has a clean and uplifting cotton scent and it comes ready to hang by a rope hanger. To activate the diffuser simply unscrew the top, remove the plastic plug, place the top back on and then turn the diffuser over so that the scented oil can be absorbed into the top (the more oil absorbed, the stronger the scent).  Measures 1.75" high by 1.75" wide by 1" deep.
