The bookmarks measure about 8 long, 1 1/4" wide and less than 1 millimeter thick. The thinness allows readers to use the markers without worrying about breaking the books binding. Each design is printed in full color using an inkjet process. The typical backyard birds chickadees, cardinals, and goldfinches are shown on the feather style, while hawks, eagles, and owls are printed on the more powerful wing style.
