Kleer VuExecutive Binder, English Leather 2 Tone with Stitching and Ribbed Spine, Heavy Duty 1" Inch 3 D-Ring with Buster 2 Inch

If I use page protectors in this binder, will they stick out when the binder is closed?

is this binder available with a spine label

Is the ring mechanism attached to the spine or the back. In other words, does it open flat?

If the ring is 1 inch, why is the spin 2.5 inches? Is the cover 1.5 inches thick? Would a 1 inch stack of papers fit optimally in this binder?
