Lenor Aroma Jewel Black Musk is an extra large 1410 mL refill of laundry scent booster beads used directly in the washing drum. The Black Musk variant is a deeper, moodier take on the Aroma Jewel line, adding a more perfumed musky fragrance to clothing, towels, and bedding while working alongside your usual detergent and softener. The large pouch is practical for households that use fragrance beads often and want fewer refills to buy. It is best for shoppers who prefer a darker, fuller laundry scent over lighter floral or soapy profiles.
