These white and blue diffusers are a classic colour.
Suitable for small spaces like your car or wardrobe.
 
To use:
Simply take out the plastic bung and turn upside down briefly to let the fragrance soak into the wooden top. Hang from your rearview mirror or in your wardrobe for a beautiful fragrance. Every few days give it another tip to refresh the scent.
 
Each one lasts a few months.
