diptyque Roses Diffuser 75 ml Refill refills the hourglass room diffuser that pays homage to the queen of flowers, evoking the fragrance of a freshly picked bouquet. Simply turn this unique object upside down and, with a simple movement, soak the wick located in the central part of the two glass sections, then place it on a table to ensure perfect air circulation. The scent drips drop by drop for about twenty minutes, in a relaxing hypnotic rhythm. Without using heat or electricity, the fragrance retains its characteristics and diffuses immediately, enchanting a room up to 20 square meters. If turned upside down four times a day, it lasts about 10 weeks and can be refilled twice.
