These parts are intended to be used in building a 1/24 model of the Lunar Module. This is a combo of all parts printed in White Strong and Flexible plastic if you are building an Apollo 11, 12 or 14 mission LM while the MESA is open but still covered with its thermal blankets (during the first steps on the Moon). For indications on building the model please refer to http://spacemodels.nuxit.net/1-32 LM
