i have a 35cm choc box and i used it to death when i first got it. it has majorly softened up and has already started the patina process...it's getting that shine. i love it, but as for size i wish it was a 30cm. i have a blk togo in 35cm and that's prob the only bag i would do 35cm in cause it's my everyday throw around bag. from now on, i think i will only do 30cm birkins. (i think....haha)
