This 'Back To The Future' notebook is great for jotting down your ideas, stories, or even time - travel plans. To use it, simply open the cover and start writing on the lined pages. The bookmark helps you quickly return to your last page. When handling the notebook, be careful not to bend the hardcover too much to avoid damage. To keep it in good condition, store it in a dry place away from direct sunlight. If it gets dirty, you can gently wipe the cover with a soft, dry cloth.
