If you decide to sell or produce Covid Immunity Wristbands, we are happy to add a link and a post to your website. Just send us a note through the contact page. We will post links to wristbands that use the design we offer. There is no charge, you can sell it cheaper than us. You don't need to buy anything from us. No royalty for the design. The mission grows and is more effective if more people chose to wear and sell the same style of Corona Immunity Wristbands.
