The pencil case has a zipper and bottom offers plenty of storage space for pens - roughly comparable to a Schlamperrolle. About the storage space for loose pins is a kind of "tongue" sewn on the four sensitive or expensive pins can be inserted into conventional rubber bands and remain firmly in place.
The cover of the Mäppchens can be completely folded backwards and still provides a greater rubber loop (eg. For attaching an eraser) and a mesh pocket, easy to stay a protractor and a ruler in the.
Overall, the pencil case is very valuable processed (no loose threads or seams, robust zipper) and is relatively thick padded, so that pins are unlikely to come to harm even in a fall of Mäppchens.
The upper material is very robust (as is common in East Pack pencil case or school bag).
Overall, I just can only express a very strong buy recommendation for the price - I myself wish I had discovered the pouch sooner :-)
