It's not magic, it's Rocketbook! And it is so freaking cool!
The Rocketbook Smart Notebook instantly connects and stores notes and doodles in the cloud with the free app. Blast pages to Google Drive, Dropbox, Evernote, Slack, iCloud, Box, OneNote iMessage, OneDrive and email.
I got the Everlast. The Everlast notebook provides a classic pen and paper experience, yet is built for the digital age. Although it feels like a traditional notebook, the Everlast is endlessly reusable and connected to all of your favorite cloud services. When you write using any pen from the Pilot Frixion line, your writing sticks to Everlast pages like regular paper. But add a drop of water…and the notebook erases like magic.
