Using this Harry Potter wall clock is super easy. Just find a nice spot on your wall, use a nail or a wall hanger, and hang it up. Make sure the spot you choose is flat so the clock hangs straight. When it comes to powering the clock, you'll need to insert a suitable battery (not included) into the battery compartment at the back. As for maintenance, keep it away from direct sunlight and water to prevent damage to the plastic case and the internal movement. If it gets a bit dusty, you can use a soft, dry cloth to gently wipe it clean. Don't use any harsh chemicals or abrasive materials, as they might scratch the clock's surface.
