Using this toilet paper dispenser is easy. First, open the door using the key for the tumbler lock. Place two standard core rolls of toilet paper, up to 5 inches in diameter, inside the dispenser. Close the door and lock it. As you use the first roll, when it runs out, the second roll will drop down automatically for use. When cleaning, use a soft cloth and a mild cleaner to wipe the stainless - steel surface. Avoid using abrasive materials as they may scratch the satin finish. Also, make sure to keep the key in a safe place to prevent unauthorized access and vandalism.
