Product Color: Black - Introduce yourself to prospective customers in a way that's unique and effective, by handing out this 4 5/8" x 3 1/8" telephone ringing sound card on sales calls, at trade shows, or by mailing them out (envelopes included)! Once opened, it plays a classic telephone ringing sound that gets everyone's attention and then they're sure to read your card, to see what it's all about. Available in several colors with stock card wording shown and has slots for inserting your standard 3.5" x 2" size business card. It's a great way to break through the advertising clutter the people you want to reach encounter every day and be heard loud and clear! You'll see that not only won't they just throw it away, as they often do with plain business cards and postcards, but they will show it to others!
