Product placement
Casetify: (a) it ACTS - its interface is operated, it generates or edits something, a visible result comes from it, or someone says what it does for them. The video shows the unboxing and application of a Casetify phone case. The packaging and the case itself are clearly branded. The creator discusses the quality and appearance of the case. Removing the name would change what happens in the video. (b) it merely APPEARS - a corner watermark, a channel or studio logo, an end card, a credit, a name on clothing, a repost stamp. The Casetify logo is visible on the packaging and the case itself. Removing it would not change what happens in the video.
