The Rocketbook Everlast is not just any notebook. While the pages made from a polyester blend feel like paper and look similar when you write and draw on them with the right pens, they can be completely erased and reused at any time, unlike paper. For this technology to work, you need Pilot's FriXion series pens, and to erase the writing, a damp cloth is required. Once the special ink is dry, it cannot be rubbed off or smudged with dry fingertips. To ensure you still have the option to save your notes, there is also a compatible free smartphone app for the Rocketbook Everlast.
