The Karlsson Wall Clock Magnetic Whiteboard is both a wall clock and a magnetic whiteboard. This means two things. One. You can create your own customized wall clock face with a bunch of colored whiteboard markers and magnets. Two. Turn the Karlsson Wall Clock Magnetic Whiteboard into a reminder notice board with a built in clock. Have to pick up the kids from the mall at 3pm? Just write a note at the 3 o’clock position of the clock.
