Germs are everywhere, and they're fast. Prevent the spread of harmful pathogens with this Ultraviolet Disinfection Bag. Using UV bulbs with 270nm wavelength, it safely kills 99.99% of bacteria in just 10 minutes. Simply put your mask, watch, jewelry, glasses, keys, or any other small items that fit, plug it to your power bank or laptop, and the disinfection starts. Unplug to stop. The built-in safety aluminum film will not leak ultraviolet rays; if the lid is closed during the disinfection process, the ultraviolet lamp will stop working immediately to ensure that it will not cause harm to the human body. Small, portable, and easy to carry so you can sterilize anytime, anywhere.
