Remember that handy imprinted calendar you keep on your desk, the pen you "borrowed" from your local dry cleaner, and the keychain you've been using for years? They all have imprints or logos reminding you of businesses you use. Those are promotional products! They stay in your mind and in use long after you visit the business, and that's just what they're supposed to do.
*39 percent of people polled remember the businesses advertised on these nifty little items as long as six months after they've received them.
