"Fold" is a bookmark design, different from the usual flat bookmarks, it is sandwiched between the pages of a book in a unique gesture, like a silent reminder. Maybe you've had a few books that you haven't finished but have forgotten about, put them in a corner and gradually lost their sense of existence. Therefore, 'Fold' is not just a bookmark, but also a kind reminder. It changes our interaction with books in an interesting way, so that we no longer neglect those unfinished books and provide an opportunity for the next flip.
