SupplyMaid Waterproof Professional Speed Cleaning Apron. Designed for Pro Cleaners Like a Cleaning Caddy Around Your Waist

How do i get the waist extender?

Is this a 5 piece set ?

Where can I buy more of the metal wire rings which allow you to attach cleaning tools to the apron?

Do you sell the wire rings that come with the aprons separately? Can you tell me what these are or where I can purchase them?
