Using this tampon and napkin vendor is a breeze. Just insert the appropriate amount of coins or tokens into the slot, and then select the item you want. After that, the product will be dispensed to you. When it comes to maintenance, regularly check the coin slot to make sure it's not blocked. Also, keep the exterior clean by wiping it with a soft, damp cloth. If the vendor runs out of products, simply open the door and refill it with new tampons and napkins. Note that you should only use the recommended coins or tokens for smooth operation.
