Magnets make your message stick -- either to the fridge at home or a file cabinet at work. I especially like this magnet because it can be a calendar, which makes it useful and visible. Calendars are the #3 leading ad specialty.
This magnet has another bonus; it can be mailed on a postcard to customers or prospects. Because there's no envelope, the mailing gets noticed more. We actually laminate the magnet to the postcard, which makes for a very slick presentation.
A magnet is also a nice referral tool. I don't know where my insurance agent's card is, but I do know my HVAC guy's card is on my furnace if I ever need him in an emergency -- or if a friend calls for a recommendation.
