Using these scent pads is easy. Just place them inside your Serina & Company Teardrop Pendant and enjoy the long - lasting scent. To maintain the freshness of the scent, you can replace the pads periodically. When it's time to clean the pads, simply hand - wash them in lukewarm water with a mild detergent and let them air dry. Avoid using hot water or putting them in the dryer as this may damage the wool. Also, keep the pads away from direct sunlight and heat to preserve their quality.
