Merchandise

I was looking on the online store and I saw this Gryffindor bag that I fell in love with and I really want it. The only problem is that it doesn't say how big it is or anything. Has anyone actually seen it or bought it when they were at the WWOHP?

It looks like this:

Would it be big enough to fit a 3 subject notebook and maybe even a thin textbook in it? And are there any zipper pockets inside? I really want to buy it but I don't want to spend money on it if it turns out that my school supplies won't be able to fit in it, especially since I take my lunch with me too.

Thanks:)
