These popular home fragrance Reed Diffuser 3 Essence Box Sets (bottle height 7cm) contains three perfumed 35ml bottles of oil. There are two sets available containing three different scents: Lavender, Ocean Breeze and Vanilla. The second set includes equally original fragrances: Green Tea, Linen and Frangipani. Reed diffusers work by placing the wooden reeds into the jar of oil and then allowing the fragrance to disperse through the reed into your room. Allow 24 - 36 hours for the scent to really develop in your room from the reed diffusers.
