The Quartet Desktop Magnetic Glass Dry-Erase Panel lets you brainstorm ideas, jot down reminders and organize your day from the comfort of your desk. Made to withstand heavy usage, this 17-inch x 23-inch panel's double-sided surface resists ghosting and staining. It comes with a marker, an accessory tray and two high-power glass board magnets. You can use the magnets to post documents on the white non-absorbent glass surface. This frost-colored self-standing panel can be easily assembled without the need for additional hardware.
