The advantage of buying a magnetic bulletin board is the product's longevity. A magnetic bulletin board can last longer than a traditional cork-backed bulletin board.
Every time a pushpin is inserted into a cork bulletin board, it creates a hole. If a pin is pulled out and replaced many times, this hole can become large and unusable. Repeated enough times, this process will cause the bulletin board to deteriorate. Magnetic bulletin boards will never have this problem. Items on the board can be repositioned easily, as many times as the user wants. Additionally, many magnetic bulletin boards have dry-erase coverings, so they can be written on as well.
