got my pair off nike.ca and it came with the same box, so the box shouldn't be a concern but from the pictures the toe box looks kinda off to me? maybe get better pictures of it? the toe box might just look funny because of the size.
i used acetone yesterday on a pair of lunar fly 306's..i didn't apply to much force and no "paint" came off but i do believe it was enough to take off the top layer of protection before i painted them. i'm no expert but it didn't have any negative effects for me.
