In Korean TV dramas, only brands sponsored by TV dramas can reveal their trademarks, and these goods generally appear in the form of various props. As for some brands that are not sponsored by TV series, the products that are inevitably used in the drama will take the form of mosaic products covering a certain part of trademarks. But it also involves other complicated issues, such as the actor endorsing the brand of mobile phone, but the mobile phone does not sponsor TV series.

In fact, most mobile phone brands in Korean dramas are Samsung, and clothes are generally sponsored by actors themselves, except costume dramas. And in Korea, this kind of advertising problem is very serious. If something goes wrong, the director will be prosecuted.
