I'm trying to decide which flap bag to get. Should I buy a black caviar 2.55 with bijoux chain and MM lock 10"x6" or a metallic black reissue 2.66? I was told by the SA at the Singapore chanel that the metallic black leather may peel away after use for a no. of years but I think the 226 size would be ideal for me. What do you guys think?
