Our 200ml Library Diffuser Refill fills the room with an eccentric and smoky scent. Made in small batches at our Wiltshire factory and fragrant with notes of Moss and Balsam Fir, the refill is perfect for keeping your living room or study, cosy. Presented in a 100% recyclable plastic bottle, the refill contains 20% fragrance – the equivalent of a ‘pure perfume’ and stays fresh for up to 10 weeks.
