You never know when your next great idea will pop up. When it does, the Polestar notebook has 176 solid-coloured pages (165 × 220 mm) for you to get creative on. The notebook’s smooth cover is made from recycled leather and has a round spine so it can lay perfectly flat. Once you’ve put your idea down on paper, close the book and use the elastic strap as a clasp and holder for your phone and the included gel pen.
