Hi there, I have the exact same 19B red flap. I checked on the tag and the code is Y33352 which translated to grained calfskin with gold-tone hardware according to chanel website. I notice that particular bag feels softer too. Are your other 2 flaps REV? Permanent flap caviar uses stiffer caviar (based on my observation only) and they always come with edge stitching while seasonal differs from season to season. For me the soft caviar doesn’t bother me at all. It’s still sturdy yet not too rigid. What bothers me is that sometimes I feel that the finish looks a bit plasticky. Sad..Hi everyone! I’m new to this thread. I have 2 medium classic flap in caviar (black and beige Claire) and the 19b red caviar also medium classic flap. I noticed the leather on the red bag is much softer leather compared to the other 2 which feels more stiff and durable. Does anybody know if the 19b red bags are pebbled calfskin or pebbled lambskin? My red bag feels soft like my mini o case which was labeled on the box to be pebbled lambskin.
