Too Many Tribbles! The K-7 Space Station, a way-station on the fringe of the Federation, was the primary setting of the classic Star Trek: The Original Series episode, “The Trouble With Tribbles.” Originally released in the 1970s, the kit is reappearing in its original form in standard cardboard packaging. Includes the in-scale teeny tiny U.S.S. Enterprise and all-new marking decals.
