Remove Diffuser from packaging, there is a general use and safety card included.

1. Unscrew the black lid and remove the plastic stopper, take care whilst doing this so as not to spill.

2. Screw on the wooden lid making sure it's on tight, push the wooden bauble down to the top of the lid.

3. You can shake it up a little before hanging in your car, however the movement of the car feeds the scent into the wood. You may want to shake it a bit when close to empty 

This smells absolutely divine.
