Pros:
It has capacity inside, I put two small books and they fit comfortably. Also, it is perhaps the only (at the time I searched) folder that has a holder for A4 papers. I could only find it externally, from Greece it was the only one. It has several compartments inside, as well as a convenient external one with a zipper.

The only negative (?) It does not have a pen holder like all the others, in the middle. Surely one of the other compartments will suit you, and it definitely wouldn't be a negative in my use. I mention it for those who use it that way.

Durability, I do not know, I do not have many requirements since it is leatherette and not genuine leather, surely at some point the material will start to open. However, its price below 20€ is very fair for this purpose. The product appears to be well-made with beautiful seams.

I consider it very fair and very valuable in this price range!!!
