Eco-friendly and sustainably sourced, Cedar Fresh presents these cedar blocks as an effective way to protect your clothing from moth damage. These solid cedar blocks possess natural oils that effectively repel moths, while the natural cedar scent dispels stale odors. This pack of 4 cedar blocks is created from 100% Eastern redwood cedar--a self-renewing and non-endangered resource. Unlike mothballs or chemically-based products, these cedar blocks are free of such harmful substances. Not only do they effectively protect your wool clothing from moth damage, but they are non-staining as well. The milled sides increase the surface area to promote fragrance and increase its natural moth-repellent properties. Use these cedar blocks in the bedroom closet, dresser drawers, wardrobe, trunks, totes, storage bins and much more. These are great for those who want the best of care for their clothing. While the natural oils prevent moth damage to wool sweaters, jackets and more, the natural cedar fragrance is a wonderful solution to the haunting, long term storage smell. With the addition of these cedar blocks in your short or long term storage, your clothing will benefit from the extra protection and refreshing smell. These cedar blocks are a great choice for anyone who prefers natural alternatives and wishes to protect their clothing from moth damage, while freshening-up their closet as well.
