Made from 100% natural North American aromatic red cedar without adding any toxic chemicals, these cedar rings effectively repel moths and insects and help dispel odors, protecting your clothing and valuables. Say goodbye to traditional mothballs. The natural scent of red cedar is light and long-lasting. While the fragrance may only be noticeable when held close to the nose, it remains effective. Each cedar ring provides up to 12 months of protection. The scent can be refreshed by lightly sanding the surface or applying cedar oil to restore its strength. Natural red cedar naturally repels moths, insects, mildew, and mustiness. It also absorbs moisture and odors, helping to keep your clothes fresh. Ideal for use in wardrobes, closets, drawers, cupboards, shoe cabinets, cars, and other storage areas. This pack includes 50 cedarwood hanger rings (1.9" x 1.9" x 0.35", hole: 0.5") that can be hung on garment hangers, placed in drawers, lockers, storage bags, shoe cabinets, or vehicles. Smoothly finished to avoid damaging fabrics, they can safely touch sweaters, woolens, and other delicate materials. The quantity provided allows for broad coverage in multiple locations. Note: Occasionally, natural cedar oils may crystallize on the wood surface, appearing as a white, powdery residue. This is a natural occurrence and indicates fresh, high-quality cedar. The residue can be easily removed with a soft cloth or brush.
