Have you ever been able to fit 1 1/2 inch binders in there? I feel so stupid for not realizing this. I bought 1 1/2 inch binders specifically for this school year because in the past my 1 inch binders have gotten overcrowded. I may have to use 1 inch binders after all this year because I couldn't fit the 1 1/2 inch one in there! The opening at the top was my main problem, although I'm sure if it were a little wider it would fit. Is the Cucciolo a better choice? I like the size of the Campeggio; it seems just right for a school bag, and this issue baffles me.
