With this Cedar Hang-Up your closets and garment bags will be kept fresh and protected from pests. The cedar closet freshener can be stowed with clothes, or attach the included hook and hang it in your closet, under your sink, in a garment bag or in a locker to add a fresh aroma anywhere. Cedar is a natural and safe mildew and moth repellant. Made without any chemicals from 100% eastern red cedar, a naturally self-renewing, non-endangered resource. Easily reactivated with just a light sanding when you notice its potency start to diminish.
