Im not sure what to get, but I want something cheap. I really love the large backpack but I think it is too expensive. I dont think the backpack is that big, can you please tell me if you have it if it is big enough for school, I need to fit a 1.5 inch binder that's lenght and width is over 10.75 inches each way?
Which one would you choose? Which color do you like best?
the tote is my LAST choice.

i like the tic tac tote better, im not even sure why i put that one there.
