Rocketbook - Core Professional Notebooks, 6" x 8.8", College Ruled, 18 Sheets, Black (EVR2-E-RC-A-FR) - Infinity Black

The Rocketbook Core executive notebook provides a classic pen and paper experience, yet is built for the digital age. While feeling like a traditional notebook, the Rocketbook Core is very reusable and can connect to all of your favorite cloud services. When you write using any pen from the Pilot Frixion line, your writing sticks to the notebook's pages as if it was regular paper. But add a drop of water, and the writing erases like magic.
