Thank you for making a difference to the lives of some of my countrymen. I would like to share my personal experience of what the bag's impact in our lives. It is indeed a very sturdy bag that withstand daily use. My daughter had used it for 2 school years and would be using it for another year if not for a tear in the front pocket (nowhere else). It had somewhat save her life when she was knocked down by a car last year and cautioned her fall (thus the tear). If it's not for the bag, she could had sustained worse injuries. But she came out without even a graze and not even a tear in her tights.
