This paper toy is designed by MTK. The rocket souvenir is a miscellaneous item in Fallout: New Vegas. These rockets were given out by REPCONN, only to be recalled when some children contracted "REPCONN Shakes" after they opened and drank the highly radioactive Isotope-239 igniting agent, thinking it was Nuka-Cola. Why radioactive rocket fuel is inside a children's toy is unknown, most likely since it was the easiest available glowing substance for REPCONN.
