The Luin Living Diffuser Refill Set contains a 200ml refill bottle of aromatic oil and 7 wooden reeds. Taking my moment to DAYDREAM is a pleasantly smooth and delicately fresh scent combination blending cotton candy, vanilla and musk with the freshness of passion fruit and red flowers. The strength of the scent can be adjusted by the amount of reeds. The more reeds you use, the stronger ambiance you achieve. The ideal time of usage for the oil is 6 months, but may last much longer than that.
