This is a stack of binders with a bunch of paper sticking out. The binders are low-poly. The little clip thing at the end is mapped with a diffuse and opacity image included as PNG format. The text on the papers is a grayscale PNG image (560x750px). Each binder is about 200 polys. Each paper is a plane.
I also have a single binder for sale. Just search 'xedium binder'.
