This is a genuine Nintendo product specifically for the Game Boy Advance. You can play without worrying about battery life. This item was stored in its original box and is in good condition. While not brand new, I believe it is a beautiful item. It's difficult to convey this in words, so please refer to the photos for your judgment. 【Contents/Accessories】 ・AC Adapter (AGB-009) ・Power Connection Unit (AGB-008) ・Instruction Manual ・Outer Box ・Inner Tray 【Condition】 ・The outer box has some minor scratches and wear. Please check the photos. ・I received this item from someone else, so I cannot confirm its actual usage history, but I believe it is in beautiful condition for its age. (This is my personal assessment based on visual inspection of the plug, cord covering, and bellows section.) ☆I have confirmed that it works with my own Advance. ※There are slight scratches on the electrode part. Please check photo 4. 【Packaging and Shipping】 The main unit will be wrapped in stretch film. The box and instruction manual will be folded to prevent crushing and waterproofed for shipping. ・Shipping via Yu-Packet Post is planned. 【Important Notes】 ・I have judged this to be a beautiful item based on my personal assessment, but as I am an amateur, there may be oversights or misjudgments.
