Legendary model! GA-400 series! Outstanding analog-digital layout! Happy color YELLOW! ❗️Battery is dead!❗️ ❗️It should work after a battery replacement, but there is no guarantee!❗️ Please understand and purchase only if you agree!❗️ Purchased new at a certain mass retailer a few years ago, but it's unused. However, the instruction manual and box are missing, so it's listed as "Like New"! You can find the instruction manual on the Casio website by specifying Module No. 5398, which is engraved on the back cover! A very beautiful item with no aging 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... Shipping may take a few days due to my circumstances! Sorry! Usually, I will ship within 2-3 days! Thank you!
