To use, remove the wooden lid of the car diffuser (and remove the stopper as well if needed). Unscrew the refill bottle and squeeze the pump on the lid once before lifting the dropper. Lift drop and place it above the opening of your car diffuser. Squeeze the pump on the dropper to release the diffuser contents. Once the dropper is emptied, return the dropper to the refill bottle and repeat the previous steps until your car diffuser oil has been filled. Once done, replace the lid on the car diffuser tightly. Invert diffuser 1-2 times to lightly saturate lid. Repeat as desired for a stronger scent. Hang the diffuser back in your car and enjoy.

Store the refill bottle in a cool, dry place away from sunlight. 

Please ensure you follow car diffuser guidelines during use. Please refer to this product’s how-to Care Guide here to learn more.
