At one point there was a rocket notebook that you did microwave to erase the ink. I don't think that notebook is available now. Probably just covering their bases if someone ever owned the old version.
It was called Rocket book Wave. It was a Shark Tank pitch.
The microwave one was the first rocket book. I love my @GetRocketbook I even bought 2 and combined them into one so I can take a week or so of notes before needing to erase.
