When you hand a flyer, people have something they can touch and keep it with them. As this is an era full of digital things, most of the stuff we receive are via email. And people get inundated by it every day, and may even forget about it.
But a flyer is different. Just imagine how surprising it can be in a city like Los Angeles, to receive a high quality, printed flyer that they can lay their hands upon. It will instantly stand out from the crowd.
A flyer will be a piece of advertisement that they can go over and over, anytime they want, without the need to connect to the internet. This can create a sense of personal touch and a personal relationship within the company and the possible client.
