RO, that means peace, calm and tranquility from the kingdoms of Denmark, Norway and Sweden. A subtle symphony of fresh grass and crumpled leaves, ambered woods and hidden blankets in the dunes. The diffusers bring subtle and stable fragrance to your home for weeks on end. To get the most from your RO scent diffuser remove the seal, place the sticks into the liquid – the more sticks used the stronger the scent - then rotate the sticks weekly, using a paper towel to hold them. Designed in Denmark, comes in nice gift box. See video Ro Scent.
