Aromatic Reed Diffusers are a natural alternative to fragrance your home. They are easy to maintain and have no lit flame. The base oil contains no alcohol or DPG, which reduces quick evaporation. We use the same quality grade cosmetic fragrance oil as in the candles. The rattan reeds have porous holes that draw the fragrance up and disperse into the air. They work best in small to medium sized rooms, bathrooms, entranceways, laundries, offices etc. Your diffuser will last approximately 6 -12 months making them great value for money.
