A set of 12 months bookmarks in 12 different colours, to mark the date, duration, rating, book title and book owner of the latest book you ’ve read.
On side A you can see the dates of the Month to mark when you started and finished reading your book.
On side B are spaces to mark the year, the owner, the title and the rating of the book you've just finished. This way you can refer to the information in future time and also, you can lend the book with your information fully stated on the bookmark, instead of the book itself.
