SUPPORT AWARENESS FOR CANCER, AUTISM, DIABETES, ETC.! Just like the sign that hangs on the outside of your business, 8.5 x 11 magnetic (magnets come standard on back of memo boards) write-on/wipe-off laminated memo boards are an effective marketing tool used to communicate your message to prospective and current customers. Sometimes, the trick to getting a customer''''s business can be as simple as whose information is the most readily available. Memo boards give you exposure 24 hours a day, 7 days a week and are placed in high traffic areas.
