diptyque Baies Refill for Electric Diffuser refills the electric room diffuser and expresses the irresistible freshness of a bouquet of roses quilted with blackcurrant leaves. It can be kept for up to 3 months after opening if the package is closed after each use. The duration is approximately 40 hours (up to 80 cycles since the electric fragrance diffuser activates 3 times in each one-hour cycle alternating 10 minutes of activity with 10 minutes of rest).
