Using this paper towel dispenser is easy. First, unlock the door with the key and open it. Then, place your paper towels inside, making sure they fit neatly with the internal guides. Close the door and lock it. To get a towel, simply pull it out from the opening. When it's time to refill, check the viewing window. If the towels are running low, unlock the door again and add more. Keep the dispenser clean by wiping it regularly with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the stainless - steel finish. Also, make sure the key is kept in a safe place to prevent unauthorized access.
