The Blackboard is a reusable writing board that is perfect for jotting down notes, marking documents, or sketching ideas. This reusable Blackboard notebook in letter size features a semi-transparent writing surface measuring 8.5 x 11 inches, equipped with Boogie Board's QuickClear technology and the Exact-Erase and Erase-Lock functions, along with a Blackboard pen with an eraser, four easily interchangeable templates, and a magnetic pen holder. Simply insert one of the four note templates (or any document) into the back and start writing on the semi-transparent writing board with the pen. The reusable Blackboard notebook templates include lined, dot grid, planner, and blank. Press the button to erase everything, or use the Exact-Erase function on the writing board and the pen's eraser to delete exactly what you want—just like with a pencil! You can also lock the writing board with the erase lock button to prevent accidentally deleting your notes.
