Using this dispenser is easy. First, mount it on a suitable surface in your commercial restroom. Then, open the door by unlocking the tumbler locks. Place the tampons in one slot and the sanitary napkins in the other. When a user inserts 25 cents, they can access the product they need. As for maintenance, regularly check the stock of tampons and sanitary napkins and refill them as needed. Wipe the dispenser with a soft cloth to keep the satin finish looking great. Avoid using abrasive cleaners as they may damage the stainless - steel surface. Also, periodically check the locks to ensure they are working properly to prevent unauthorized access.
