These are three unflown Flight Systems, Inc. D-1.12-0 model rocket motors in a package for retail sale. The "D-1.12-0" signifies that the power of the motors is in the fourth highest class (out of of seven) established by the National Association of Rocketry. They are made of pasteboard and contain non-explosive propellant. The electric igniters used to ignite the motors are missing. Each motor is used only once to power a model rocket.
G. Harry Stine, a pioneer in the field of flying rocket models, donated them to NASM in 1973.
