Shipping will be via standard mail (excluding Saturdays, Sundays, and holidays). Please refrain from purchasing if you are particular about simple packaging. Shipping will be in an envelope, without bubble wrap. Waterproofing will be done. (Packaging will be simple and may use recycled materials.) (Game Boy software under 3,000 yen) Since many items are shipped via standard mail, I am not responsible for any undelivered accidents. If you require compensation, I will change to Nekopos (anonymous delivery) for an additional 150 yen. Software only. Operation confirmed. The terminals have been cleaned using a contact cleaner. Please note that there may be cases where the software does not start properly due to compatibility with the main unit, but I cannot guarantee this. Battery backup function is not guaranteed. *Since this is used software, there may be cases where reading is poor. I always check the operation before shipping. *Please purchase with understanding as this is a used item and has been stored at home. Please refrain from purchasing if you are nervous or seeking perfection.
