The Lenor Unstoppables Fresh scent boosters are small fragrance pearls designed to be added directly to your washing machine drum before you put in your clothes. This 495g XL pack comes in a plastic bottle with a dosing cap, allowing you to control the scent intensity by using up to three caps per load. These beads dissolve during the wash to leave your laundry with a crisp, clean aroma that lasts longer than traditional softeners, making them a practical choice for anyone who wants their fabrics to stay smelling fresh for an extended period.
