A Flyer is a single, unfolded printed sheet. This is used to draw attention to an event, service, product or idea. The flyer usually has a very simple message that can be delivered quickly. The flyer is usually printed on paper size of 8.5 "x 11" so its cost is low but you can make it into any size that is easy to handle. The purpose of the flyer is to capture and read so it is possible to print it in full ink color, but there is no such rule so you can print it in any ink color.
