I‘ve had mine since January and it looks brand new. However, I rotate my bags (I’ve worn it maybe 3 times every week since January), carry very little and I use a bag insert, the 2mm felt by Samorga. The thinner one takes up less space but is too thin. I remember that a fellow tpf er mentioned that the bottom on her Buci started sagging because she carried heavier things in her Buci. And she had no organiser.
The flap on my Buci was tilted to one side when I received it. I am storing it with a bit of rolled kitchen paper under the side of the flap that’s too low in order to lift it. It will never be completely straight but it is fine and I‘m so happy that I did not return mine at the time because otherwise it’s perfect.
About Epi leather in general, it is very hard wearing but a scratch cannot be buffed out and will appear whiteish. Hope that helps!
