I did return a Rosa calf to NAP because it arrived with marks, I thought they happened during production I'm not sure what every day use would look like. I am not a seasonal bag person though I know many are I often see people get certain colours for certain seasons. I just carry what I like when I like in what colour I like any time of the year. The only thing I check for is which leather to use if it's raining because some don't show marks.
there seemed to be a blue biro mark. and small self colour "scratches", are you based in the UK? I wonder if i had yours

I am not either but it pours with rain and I dislike my bags get ruined. Do you use any Mansur Gabriel when it has rained?
