That internal BB is less than satisfying. If I recalled ( I don't have pic to shown the internal as I already build up the bike) correctly it should be smooth and no wrinkles like that. You might want to show it to Alisa first before you start the build.

Yep I sent email to Alisa. I will share the reply when I get.

It's Fidlock single toolbox(https://www.fidlock.com/consumer/en/twist-single-toolbox/09646-p00002-blk)

I can replace the box to the bidon which support fidlock system.

very nice, thank you.

Got a reply from Alisa, and here is the part;

Confirmed with our production manager , the uneven BB inside surface will not effect the safety of the riding , you don't need to worry about it . 

sooo... I will try to believe her(and the production manager).

I don't remember who it happened to but there was one person who had doubts about the manufacturing quality of the carbon and the salesman told him not to worry when the problem really was dangerous. But for your case, I cannot comment.

Yeah, this's a classic way to say "fuq off." They talk to the manager/engineer/god/Lucifer, and everything turns out to be perfect and in order. "No worries, friend, buy more frames." Quite common for chinese carbon manufactures sellers.
I guess if it concerns you a lot, the most reliable option is to show it to someone who might have some skills to test/diagnose. Or seek help from internet experts here and there (I'm not the one, unfortunately).
Otherwise, build and test yourself. You could find some weak points after assembling.
