These binders are stunning. Because the sides seem to made of plastic only and not cored with cardboard they are unsteady and difficult to take off the shelf. The mechanisms seem to be good quality up to the job.
Binders are sturdy and easy to grasp. I was pleasantly surprised at the number of pages (in protectors) the binders accommodate without feeling bulky. The spine label and the clear front pocket for a title page are nice features.
