Very Fine (VF): A few light creases may be present at an edge/corner or on the inner surface of the cover (such as when a “thumb” presses down on a module cover and creates semi-circular stress lines). There should be no folds or hard creases. Corners can have other wear such as slight “rounding” or “abrasion”. On modules or staple-bound items, the edge of the spine may have some slight abrasions to the outer surface layer, though the spine itself it still strong and intact (this is a sometimes common occurrence from the cover being opened repeatedly). For perfect-bound accessories, light vertical stress lines are more prominent (though not extensive). Staples may have the slightest hint of rust, but should still be at least 90% rust free with no rust stains on the pages. Maps / inserts may be detached -- there can be a few marks written on the these, but they should still be minor and not extensive (no highlighting or marker). Again, judgment must be used as each item is unique. Perhaps two corners may have tiny 1/16” creases at the extreme tips or there could be one very light ½” crease.
