Satchel used as binder for teachers. The pockets are practical, easily accessible and fairly large capacity (easily one arranges them in notebooks 24X32). It seems solid: used on tar but also on a dirt road with fairly high pavements, so it is put to the test. Time will tell if it withstands all this, but after three weeks of ill-treatment, no signs of fatigue. Beware, if you want to put students files, notebooks of the day ... for a class (teacher in primary school) should preferably be provided as a rolling cart instead remains limited and is unlikely to bear in the bag weight . If corrections are made largely to school, the bag is perfect to carry the rest. Seems like for all my colleagues have expressed interest and came to get a closer look! Very good price / quality ratio and ultra fast delivery.
