We recommend you only use a Pilot FriXion pen or marker with your Rocketbook notebook. The FriXion ink is washable and that, in conjunction with the synthetic paper, is what allows the Rocketbook Core, Fusion, Flip, Mini and Orbit to erase using only a cloth dampened with water, and the Wave to be cleared in the Microwave (See Wave cleaning here).
Note: The FriXion pen ink is heat sensitive and will turn invisible in temperatures above 140 degrees F. Accidental erasing of your Rocketbook notebook can occur if your Rocketbook notebook is left in an environment like a hot car.
