A mini reed diffuser is a type of air freshener that uses natural reeds to disperse perfume oil into your space. The reeds absorb the oil and release the scent into the air, providing a pleasant aroma. To use a mini reed diffuser, you insert the reeds into the bottle, and the oil will naturally diffuse into the air. You need to flip the reeds once a week to refresh the scent. The mini reed diffusers come with a screw top so you can travel with them and enhance the ambiance of hotel rooms or other spaces.
