Regardless of what side of the vaccination aisle you are, as Americans, we must never get into the business of going door to door pushing vaccination. The text reads, "We identify as vaccinated, and we identify you as trespassing. Don't even think about knocking."
This item is ok for outdoor use, however if it will get wet, we recommend using a waterproofing sealer on it. We recommend Command Strips to attach to your door. You can find them here.
