Positive I noticed that the material of the portfolio is quite strong and that the slide rails for the documents are very well secured. Practically, I also think the small slits in the top and bottom of the right part of the portfolio, with which you can fix the cover letter so that it smiles against the employer-to-be when you open the folder.
The folders come by the way space-saving and well-embeddable in a stable, precise carton. So you can see the things problem- and especially kinks store up to next application in the family or friends.
Conclusion: I can only recommend this application folders.
