I purchased the Sistina GM last month and have been using it everyday. Being that said, I just want ya'll to know that I take very good care of all my purses.I just want to know if it's normal for the flap to have creases after just a month of use? I have the Mono Griet and the flap is still flawless after 2 years. Pics below with my beautiful Sistina wallet to match!! Please advise.
