The resin parts are solid, with slightly soft details. Each astronaut is molded as a single piece, with the PLSS and hoses molded in place. An additional rock bag, a soil collection scoop and two Hasselblad cameras are also included, as is a resin base. All resin parts, with the exception of the base, are still attached to their pour plugs. No airholes are evident in my parts. The metal parts are small wires for each figure's PLSS antenna. The instructions are detailed drawings showing how each figure is to be painted and posed. A couple of additional color photos of the prototype model are also included to assist with the assembly and painting.
