Review on FeverDots: 30 Shape Temperature Indicating Body Stickers - Black to Pink, 7mm Size (Pack of 30) by Trey Harvey

As a business owner whose employees have been disabled due to Covid these stickers have given me extra confidence that we can contain and isolate any outbreaks that may arise. The point on each of us was black or purple when we started wearing them. Then a person's fever spot became light pink throughout the day. Of course they had a fever. We could quickly see who was sick and isolate them so the rest of us didn't get sick.
