Hi - I just got a Birkin 30 in Mysore and something odd is happening that Im not sure if it will ruin the shape of my bag in the long run. All my other Birkins are in Togo or Epsom so Im not sure if it is due to the leather. This Birkin is about 3-4 weeks old, as in any of my Birkins, I put the lock on right when I receive it on the front where the lock goes. As time went on, I am seeing that the front panel of my bag starting to droop forward as if my lock is too heavy. Does anyone have that problem? Do I need to take the lock off each time after I use it? (That would be annoying.) If I leave the lock on, will it keep pulling the front panel forward?! Any advice would be great, thank you!
