I do like to take notes and quotes while I read a book, but often the book is too precious to smear with pencil in it. And of course I also want to be able to put a book away without damaging the back, while marking where I stopped.
Why not combine both? In this 24 page booklet you can take notes and mark where you stop reading. It is just as thin as a bookmark.
The booklet has 24 blank pages and is approximately 7.5×15 cm and about 1.5mm thick. It is a handmade item so the measurements will vary a bit.
