Internal Pockets

As you can see from the photo, there are three pocket designs. Each has it's own advantage:

The Straight is great for folios, as it will hold the notebook cover more firmly in place.

The Boarding Pass is, as the name suggests for things like boarding passes to be slipped into it and easily found and removed.

The Secretarial pocket is the design I will use by default if you do not instruct me to use one of the others. It is still good at holding a notebook's cover and also keeps receipts, notes etc safely, but is easier to access than the straight.
