This 1300 Traditional Natural Cork Bulletin Board withstands repeated tacking with its self-healing, natural cork surface. Tack your flyers, notices and other documents to the surface. Remove the tack to watch the hole disappear, providing years of reliable service under even the heaviest of use. Pins, staples or tacks can easily be inserted without falling out over time. Cork surface is laminated to a 3/8" thick, sealed-back fiberboard for durability.
