This is a collection I purchased and stored for a long time. Power-on tested (batteries not included, CR2032). Buttons respond, but not all have been checked. Sound works. When shaken, the pedometer seems to be counting. The screw in the battery compartment is rusty. This is a very old item, so it is considered junk. 1998 Pocket Pikachu, yellow, with clip for easy carrying. - Model Name: Pocket Pikachu - Color: Yellow - Year of Manufacture: 1998 Pokemon Pocket Monsters Pocket Monsters Pikachu Thank you for viewing.
