The Lenor Spring Awakening In-Wash Scent Booster consists of laundry perfume pearls designed to add a lasting fragrance to your clothes. These beads release a scent characterized by notes of patchouli and spring flowers, which remains noticeable for up to 12 weeks while your garments are kept in storage. To use them, you simply add up to two caps of the pearls directly into the washing machine drum before loading your laundry, allowing you to adjust the intensity of the fragrance to your preference. This 270g container features a squeeze-and-sniff cap so you can check the aroma before use, and the formula is compatible with all fabric types.
