Purchased during the year, because I have a 4x4 boy, this binder ended the year with CP and currently Ends EC1 having retained its solidity. It is a small school bag, for now well adapted to the needs of my boy. It easily holds A4 pouch, a text book, two small notebooks drafts, a notebook and a small kit. By cons, do not expect to load it in books or binders. I believe that this binder will soon find its limit in terms of capacity during the next grade. See next year, I would complete the comment if necessary.
Otherwise, it is very strong and compact, especially take time to read the dimensions in the product description. Personally, it makes the job well. I am happy with this purchase.
