Nicki Tutorials is one of the first I've seen actually declare for each product on screen the source. Probably because she's in a country with stricter rules.
Sure it's only on screen for a second and there is a loophole if someone bought a product from a brand they have a business relationship with (like so many gleamers do now). But still nice to see someone being honest whereas many others claim it would be impossible and ridiculous to do so.
