ok, i've been SUPER careful with my new tutti ciao which i've only had for 2 days now. i don't know what it is, but on the grid-like thing on the material, my bag is starting to get a slight grey color on the lines of the grid. so instead of the background all being white, you can see the grid in the background. it's very faint, but it has me really worried, as i've only carried this bag twice so far, and i've been really careful with it. if you buy tutti, make sure you pick up a magic eraser as well! it may just need to be cleaned every so often to keep it white.
