Inspired by the movies and video games set in post-apocalyptic wastelands, this t-shirt features a Radioactive symbol that's began to decay. Designed to appear like flaking paint and rust, this design is great for kids who love games of a similar nature... But that's not all. At night, when you turn out the lights, the design will GLOW IN THE DARK! So for those who love science, post-nuclear war movies and video games, this t-shirt will make a fantastic gift for them to wear during the day... and night!
