(i.e. The advertisement budget of the company is 5,000 per month. The director consider this amount as trivial)
это мéлочь/мéлочи/пустякú

( мелочь/мелочи is usually used when it deals with money or material resourses).


Worker: - Boss, we should first write a report to public authorities before starting the applications.
Director: - These are details!
(i.e. The director does not consider that this action is important).
[это] пустякú

Man flirting with an unknown woman: - Do you want to go for a coffee
Woman: - I am married
Man: - Details.
(i.e. The man is trying to impress by saying that he does not care about her marital statues he just want to flirt with her).
[это] пустякú

Generally, eрундá is the same as пустякú, but sometimes it can express not only unconcern, but also negativ attitude .
