Tesco Logo transparent PNG StickPNG Reed Diffuser 200ml Refill French Pear. GEORGE & EDI reed diffuser fragrance refill oils are designed so you can reuse the vessel you received when purchasing the reed diffuser set. The 200ml refill oil comes with two new sets of black reeds (10), as the reeds will deteriorate over time and not work as efficiently, so we recommend changing with each refill Please note: if you are purchasing a different fragrance to what was previously in your diffuser vessel, we recommend you either purchase a new reed diffuser set or thoroughly clean the vessel before reusing as the previous fragrance will affect the new fragrance
