Hi everyone! I was recently introduced to Tokidoki bags, and I'm hooked on the cuteness. Just recently got myself a Tutti Buon Viaggio, with a good placement. I am so scared to use by new bag because, I'm afraid it will get dirty fast. But my main concern is that I want to use this as a bag for school to carry my books and binders, and I am wondering if the bag (mainly the bag straps) can support the weight of my binders?? I don't want to rip/damage the bag. Anyone used the Buon Viaggio as a book bag, opinions? Thanks.
