Using this case is a breeze. First, carefully place your Raspberry Pi 4 Model B inside the case, making sure the main - board is in close contact. Attach your Pi camera to the dedicated camera port if you want to use it. When you're not using the ports, close the magnetic top to protect them. As for maintenance, simply use a soft, dry cloth to wipe the case clean. Avoid using harsh chemicals as they may damage the Space Grey finish. Keep it in a dry place to prevent any corrosion of the aluminum material. That's all you need to do to keep your case and Raspberry Pi in great shape.
