The Chippy™ Lightweight Wire-Bound Sketchbook

Love how you can customize which edge the binding is on. I prefer spiral to other types of binding because it's truly lay-flat when you draw. I do wish the chipboard cover (or at least the back cover) was more rigid - but I won't dock stars because the product is literally named "lightweight" and they used lightweight chipboard... Thicker 0.050" stock would have been better IMO.
