This is a set of five model rocket motors packaged for retail sale. They are made of pasteboard and contain non-explosive propellant. A motor is used only once to power a model rocket. The Krusix firm in the former Yugoslavia manufactured them in 1970.
G. Harry Stine donated this artifact to the Museum in 1973.
