Bluetooth compatible G! Lightweight, mid-size! Cool, deep green! ! Battery is dead! ! It may work with a battery replacement, but I cannot guarantee it! Please purchase only if you understand this! Purchased new at a certain mass retailer several years ago, but it's unused. However, the instruction manual and box are missing, so I'm listing it as "Like New"! You can find the instruction manual on the Casio website by specifying module No. 5554, which is engraved on the back cover! It's a very beautiful item with no age-related deterioration! The main body only will be shipped via Yu-Packet Post, and changes are not possible! Even during transaction communication, I will unfortunately prioritize the first person to purchase! Thank you for your understanding... Thank you very much!
