Elegant dark blue plastic bag with "comfort thickness of 2 cm" allowing to put a little more, almost as much as in a shirt with wide backrest. The plastic looks solid thereby use it to carry documents in a meeting or other as it is class. For storage of workbook documents, it lacks a label door. Remains the price a little high. Contrary to another comment, I have had no problems opening the carton. It was very high and well protected by paper carton bottom cover. Maybe the other remark was beneficial!
