The bag came slightly before the estimated delivery date which is really good, and to add to that, the product is amazing! I love all the comic designs on the bag and i always stare at them during lessons when the topic gets boring and the teacher's words start to sound more like 'blah blah' than anything interesting. So, anyway. For a year 11 school bag it's really nice and it's big inside. You can get all your books in and there's probably room for a PE kit inside. There is an inside pocket and an outside pocket and both are secure. The strap is adjustable so that you can have it just above your thigh. The only complaint i have about this bag is that because it's sliding against my thigh when i walk, the back of the bag has gotten fainter (just in one or two days too) so be careful with how you handle it. Don't slide it across ground if you want it to stay pretty. So it does look slightly odd with the back being faint and the front being bold, but in time the front will be faint and it'll still look nice, maybe even vintage.
Overall it's a really nice bag! I love it.
