Good and comfortable backpack

The backpack looks just so colorful as in the picture and is to also surprisingly large (I had imagined him much smaller).
My school stuff I get tucked easily into the backpack. The small four pockets that are located on the outside are also really handy.

However, there is still one two shortcomings. The drawstring to close the backpack wears off after a while and a white substance emerges.
The second defect is that the backpack a floor of "leather" has, which is sewn to the fabric of the backpack. For me, it has happened that in one corner of the backpack the "leather" is torn and I now have a hole.
The positive is that can not fall out because of the backpack even has an internal fabric.

Around a recommendable and stylish backpack :)
