I think 他这个按钮，他 （真皮？）不合宜，（意大利人？）不同意嘛。 Although I'm not sure that a button would have genuine leather so may be wrong. I think after 那个 it might be a japanese or italian name. perhaps骗哪个。。说。. I also hear 办不成 rather than 话不成but my native language isn't chinese. .. 我只是抛砖引玉

If can use 'or not' after it, the you should probably use ob. Or you can use the rule if you can replace 'if' with 'whether' then it is ob. I don't know if I can come (or not). Here you should use 'ob' Can you bring some drinks, if you come. Her you should use 'wenn'

Here are some examples where you might use this question. 1) A: My partner thinks I'm very unromantic B: Well do you ever send her flowers? A: No I've never sent her flowers 2) (Policeman Interviewing a suspect) A: We found some flowers in the victims house. Do you ever send her flower? B: No I never send her any flowers. In these circumstances you're finding out whether the person has either 1) never does it/has done it or 2) does do it/has done it at least once. It's a bit like the opposite of 'never' (it has happened at least once) but with this meaning, you can only really use it in a question. If I was translating into chinese I would probably do it as follows. Do you ever send her flowers? (你给她送去过花吗？） Do you send her flowers? （你(经常）给她送去花吗？）
