The Question Nobody's Asking About the Traveler's Notebook

I take a look at the Traveler's Notebook, a unique way to carry all your notebooks at once. I go through my set up, overall opinions about the Traveler's Notebook, and also ask the question: what happens when the notebooks are done? Something completely not concerning, I should probably just enjoy the notebook, but I can't help but wonder what the inserts look like when they are no longer in the Traveler's Notebook.
