Glow-in-the-dark Bacterium
Not much is know about this 

monotrichous bacterium. But it is happily swimming around with its single flagellum. It also appears to be modified with green fluorescent protein because it glows in the dark! When not swimming in the dark, this bacterium will be white. Also available with a metallic silver print.

This 2-ply cotton fitted face mask is designed, handmade, and printed in Ann Arbor, Michigan. One size fits most adults.
