My only complaint is that some pages have a small dark fleck or two on them. It's not a problem for my use but if you want perfection this may not be the best option. For me though it's fine and a decent value.
This card stock works well in our copier/printer. Not really recommended for inkjet; generally for laser. Surface is really not absorbant enough for inkjet inks to dry. It is easy to be confused with the weights of heavyweight papers. Card or Index stock is NOT the same weight as Cover stock. Card/Index stock generally comes in 90 lb 110 lb and 140 lb weights while Cover stock generally comes in 65 lb 80 lb and 100 lb weights. For comparison sake: 90 lb Card/Index is somewhat similar to 65 lb Cover stock 110 lb Card/Index is somewhat similar to 80 lb Cover stock and 140 lb Card/Index stock is somewhat similar to 100 lb Cover stock. Be sure to read the label and know what you are getting or you might be disappointed.
