Your daily mission is anything but ordinary. Fortunately, there is a Rocketbook Orbit Page Pack for every phase of your journey. Not to mention that they are designed for the bumpy and unpredictable ride. The metal loops that hold the Page Packs together are secured by magnets embedded in the back of the Orbit. They can be easily pulled out and swapped, yet are strong enough to keep your pages secure. (Orbit Pad not included, Pilot FriXion Pen and microfiber cloth not included). When you write with any pen from the Pilot FriXion line, your writing will stick to the Core pages like regular paper. But add a drop of water, and the notebook erases as if by magic.
