Volumes 1 and 2 are in one binder and Volumes 3 and 4 are in the second binder. I do not have the slip cases for this set. There is tape residue on the spine on both binders (see pics 3 and 14). On pages i-x, the pages are damaged either by a small stain at the top of the page or some page creases at the bottom. I took pictures of the worst of these. As the pages go up in page numbers, the stain and the creases diminish (pics 16, 17, 19). On the last page of BOTH sets, there is some overall stains on the page (see pic 24).
