I don't understand the language, but it appears she was given a strip of power chain to install herself at home?
I was wondering that, too

. Since it's a clear powerchain, she might expect the old one discolor soon and it to be easier taking care of herself ...
Any Russian natives or knowledgeables to enlighten us about that?
