Who says a pen can't be a bookmark?
It's a pen and a bookmark in one. Another clever cute little thing. Only you shouldn't use the pen in marking/highlighting parts of your book. Never ever write on your book. It would ruin the pages, and of course, it would make it look untidy. If you have to save important messages, then grab a piece of paper or a notebook and jot down what you have to.
I got this from a swap partner in France.
