EXCLUSIVE! The shirt that you reinvent, every minute you wear it. A UV-light keychain lets you "draw" anything you like on the shirt, triggering the exclusive ultrabright glow-in-the-dark ink; your artwork will glow for 10 minutes before fading to allow you to create a new design or phrase. Machine wash. 100% cotton. Imported. S-XXL. Specify Blue or Black when ordering.
