Using this Bradley toilet paper dispenser is easy. First, open the door with the key. Then, place two standard core rolls of toilet paper up to 5 inches in diameter inside. Close the door and lock it. When the first roll runs out, the second roll will drop down on its own. For maintenance, clean the dispenser regularly with a soft, damp cloth. Avoid using abrasive cleaners as they can scratch the satin finish. If you have any problems with the tumbler lock, contact a professional locksmith. Also, make sure to keep the dispenser in a dry place to prevent rusting.
