Using this personalized light box is easy. First, find a suitable spot like your table or desk to place it. Then, connect it to a desktop computer, laptop, or power bank with a USB input since it doesn't come with a wall charger. You can turn the light on or off and adjust its brightness using the switch. As for maintenance, keep it away from water and dust. You can gently wipe it with a dry cloth if it gets dirty. Remember, due to manual measurement, there might be a small difference in size. If you have any questions, don't hesitate to contact us.
