Rocketbook MATRIX Erasable Graphic Page Notebook
Designed for future doctors, engineers, and mathematicians, the Matrix makes it easy to create and share hand-drawn graphs, sketches, and diagrams. The reusable graph paper pages provides a strong visual aid for your work without being a distraction. More than just a lab notebook, the Matrix works with the Rocketbook app to scan and digitally share your notes with anyone in the galaxy or to transfer your work to a computer. Plus, the innovative synthetic paper allows you to write smoothly with a Pilot FriXion pen, then magically wipe your pages clean with a damp cloth to reuse again and again.?
