Dry-erase planner board features a monthly format and two ways to post notes and reminders. Write them in with a dry-erase marker (sold separately) or tack them on with a magnet (sold separately). The monthly format features large unruled day blocks (2-9/25" x 2"), Sunday-through-Saturday scheduling, a place to write the date and month, and a ruled area for notes numbered 1 to 31. Color-code key along the bottom can act as a key to identify four colors for color-coding. Laminated dry-erase surface resists stains and ghosting so you can reuse again and again. Board is made with a steel sheet core, cardboard back and nongloss melamine frame with black corners.
