These fantastically nerdy flasks from Etsy seller Lady Rene celebrate all things nerd. There are superheroes like Superman, Batman, and the Teenage Mutant Ninja Turtles along with a map of Terminus from The Walking Dead. Each 6 ounce flask is covered with a vinyl decal and laminated with PVC for a layer of protection. You can even have the flasks monogrammed with a name or initials.
See more flasks after the break.
