If your reed diffuser is running low then this is the best option to top up without having to buy a whole new set.
Reed diffusers are an alternative way to freshen up your house without lighting a candle! The 150ml refill bottles should last around 3-4 months with the turning of your reeds often. These bottles come with a child proof screw lid aswell for safety.
Please note heat will make your reeds soak up the liquid quicker.
