Did you know that UltraViolet light is used for disinfecting, killing germs, bacteria and viruses?

It’s designed specifically for disinfecting nearby objects with UVC light, such as face masks, keys, wallet, glasses, phones, goggles, pens and other commonly handled items.

It has an internal battery that can be charged from any USB port or charger, so the light can be placed anywhere. You can use it when plugged into the USB as well, in case you want to use it when the battery is low – you don’t need to wait for it to charge.
