This listing is for one unopened Japanese copy of Pocket Monsters Stadium Gold and Silver, the Japanese equivalent of Pokémon Stadium 2.
Japanese N64 games were never sealed in plastic, but can be judged to be unopened based on any wear on the hinge. This box has never been opened.
Please see the high-resolution scans and pictures, and note the wear, including a crease on the front.
The card pictured is the exact card you will receive.
