Query: This Backpack is Great!!!

I absolutely LOVE these backpacks! They are SO roomy. When I first got it, I was a little disappointed because it looked smaller than I had imagined. But once you start filling it up, it expands like crazy! I can easily fit all of my various binders and folders in it quite comfortably. There are also a lot of little pockets in one of the compartments for your cell phone, keys, all of the stuff you tend to loose. The hardest part was probably picking a design! There are so many cute ones. I highly recommend this backpack.
