CleanKey works as a handy keychain you can bring anywhere, anytime to press buttons, open doors, and pull levers. No more direct contact with contaminated surfaces! With 62% Copper content, CleankKey is inherently antimicrobial, killing or slowing down the spread of microorganisms including bacteria, viruses, protozoans, and fungi. It comes with a retractable carabiner so you can attach it to your daily stuff.
It sells for around $20. I would expect we’ll see a lot more alternatives like this, possibly with even higher copper content. I think the brass alloy was chosen for strength though.
