I have a few things to say about the 17b red caviar from my personal experience and hope they’ll help you make a decision. I have encountered 3 different bags of 17b red and they seem to have very little but noticeable leather creases especially along the edges on two while the other i wasn’t too happy with the leather.
The first is my mini, I only notice this a few weeks ago when I took it out. I rarely use this so it spends almost 95% the time in its box and I bought this brand new in 2017.
I’m thinking this has to do with storage although I don’t have this issue with other bags despite storing them all the same. I think this has to do with the stiffness/stitching along the edges.
Then the m/l I have I also notice this at the right corner on the back.
I purchased a jumbo almost two years ago preloved and returned it because I remember the quilts looking flat despite showing up super puffy in pictures.
I don’t know how much the creases on your jumbo bothers you but those on mine didn’t for me. I personally don’t mind and have no issue with the crease on your jumbo. Keep in mind that maybe this is how 17b red leather might be as these bags get older in age.
It comes down to how much that crease bothers you. If you can’t stand it and seeing it make you unhappy or feel cheated for spending so much money then return it because as long as you can justify why you’re returning it, you won’t have FOMO after and will wait for a better one.
