Navigate this germy world more carefully with the Careful Key. Use it, instead of your hands, to open doors, press elevator buttons, use store checkout terminals, and more. Because it's made of a brass alloy that is 70% copper, a naturally anti-microbial element, germs cannot survive long on its surface. This 3 inch tool fits comfortably alongside your keys, ready to function between your hands and potentially unsanitary surfaces. Made in Portland, Maine by Zootility.
