Sony's PocketStation is a handheld device with game data management and clock functions. I also replaced the battery. I feel like the top part is slightly open. (It doesn't seem to affect the operation) Please check the condition of the main unit in the photos. *Please consider this a "junk item" due to it being a used item, and refrain from purchasing if you are looking for a perfect item. I try my best to communicate the condition and operation, but please understand that this is a simple assessment by an amateur, so please be aware that there may be oversights in the condition or operation. Also, please forgive any subjective differences such as "more than I expected" or malfunctions due to the operating environment. Also, please check the condition of the product in the images, and if you have any questions, I will respond to them at any time in the comments, so please feel free to ask. Please understand the above and purchase with no claims and no returns. Thank you for viewing.
