From Takara comes this vintage handheld video game - Operation: OK, from the 1992 movie, Godzilla vs. Mothra, aka Godzilla and Mothra: The Battle for Earth. The game is in good condition and still works with one LR44 battery.
The game still works (see video) - but don't ask me how you play it!
The item is approximately 5" x 3".
