After reading the comments of customers I bought these shirts and I admit that now I no longer use but a few! Not only the colors are beautiful but increasingly these shirts are very convenient because they do not open completely, they are sealed on the left side and the bottom thus avoiding that documents but also slide the window is a very ^ great idea because then there is no need to open each time the shirt to see what was inside. They have become indispensable to me at work (I teach and it helps to have everything at hand in a wink, like the papers to grade per class for example and photocopies depending on the course, etc ..) and they are very convenient for everyday documents. Ideal for classification. I had ordered twice and I will order again.
