This is a vintage Star Trek checkbook case by Paramount Pictures.
It is black with a marble pattern and features plastic inner panels, a gold-colored print of the "U.S.S. Defiant", and the words "U.S.S. Defiant" and "Star Trek: The Ships of Starfleet Command".
The case measures about 3.25" long and 6.25" wide.
This case is in very good pre-owned condition.
