A high quality 50ml round glass diffuser bottle. DIMENSIONS: Diameter - 55mm Height - 69mm Caps and Reeds are sold separately and are not included with the bottle.  How to make a Reed Diffuser: - The ratio we advise is 25:75 (25% fragrance oil & 75% base oil) - After measuring your ingredients, mix them together in a jug or glass - Pour your finished liquid in to your Reed Diffuser glass - Pop the bung in the neck of the bottle & then screw on your cap - If you are using straight away, screw on your cap & then put your reeds in to the glass - Allow 24 hours for the liquid to soak up the reeds fully & give off the scent.
