What type of pen to use

We recommend you only use Pilot FriXion pen or marker with your Rocketbook Everlast. The FriXion ink is washable and that, in conjunction with the synthetic paper, is what allows the Rocketbook Everlast to erase using only a cloth dampened with water

Note: The FriXion pen ink is heat sensitive and will turn invisible in
temperatures above 140 degrees F. Accidental erasing of your Rocketbook Wave can occur if your Rocketbook is left in an environment like a hot car
