It’s not recommended to use the rubber tip eraser on the Rocketbook pages, it can wear the page making it hard to write on those specific spots over time. To make small corrections, you can use a water brush pen and a small make up sponge to then erase and dry. Or just wet a small part of cloth and use it over your finger. Enjoy! I have accumulated several Rocketbook products over the years (planners, index cards, sticky notes 😅) I wish I would have known of this when I was back in school.
