● Product Details
• Compatible Models: Game Boy Color / Game Boy Pocket
• Manufacturer: HUDSON

● Condition
• Outer Box: Shows signs of age-related damage and dirt, but a box from that era is extremely rare.
• Main Unit: No noticeable cracks, but there are minor scuffs due to its age.
• Operation: The built-in NiCad battery is likely depleted, so this item is currently listed **assuming it will be used for collection purposes or as a grip only**. Power-on functionality has not been confirmed, so please purchase only if you understand it is being sold as junk.

● Shipping
The item will be carefully packaged to prevent the box from being crushed and shipped via Mercari delivery.

How about this opportunity for Hudson fans or those who collect peripherals from that era?
