Magnetic whiteboard eraser features a built-in, refillable bottle of spray cleaner. As you would with any board eraser, use the rigid felt surface when dry to wipe your board clean; and if there are any shadows, streaks, stains or ghost-marks left behind, simply press the front-face button to finely mist the surface and wipe again to get rid of them. For easy access to the refillable bottle of spray cleaner, the eraser's body features a snap-open design, and the bottle features a standard, spray-bottle twist cap. The body is also magnetic to allow for convenient on-board storage and right-at-hand access.
