I use this book in the study to my scripts, notes, writing materials, etc. to have in a compact form with me. The processing makes a very stable impression and I think that I can use the wallet for a long time. Practical: The supplied block can easily be replaced by another, whether it is bound by left, right or top. Also usefully some adhesive labels supplied to label the compartments to deposit his name and contact information for the case of loss in the portfolio etc.
However, one point of criticism I have (hence the star deduction), the division of pockets for pens etc. Front is not quite optimal. In my opinion, it would have needed a little more space for pins (see photo above). Just when the professor several different colors rolls over again essential if you still want to see something in his sketches later.
