I bought one of their D-Ring binders with a slip case for my 52 Bowman set. And then I purchased a few of their divider/page turner inserts to separate the raw pages from the graded pages (I have my graded cards in four pocket pages behind the raw in nine pocket pages). I wanted a sturdy divider between the two so the hard edges of the graded cards didn't indent the raw card page right next to it.
Looks great and binder feels more "high end" than a standard office binder.
