Smith & Co Diffuser- 200mlReed Diffusers are a simple and effective way to diffuse continuous fragrance throughout your room.

Avoid placing your diffuser close to windows or air conditioning units as these will speed up the diffusion time. Avoid placing in direct sunlight as this can cause liquid to discolour. Size: 200ml.
