Legendary model! GA-400 series! Striking impact with yellow and navy blue! Unique rotary switch function! ❗️Battery is dead!❗️ ❗️It may work after a battery replacement, but we 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 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, we will unfortunately prioritize the first person to purchase! Thank you for your understanding... Shipping may take a few days due to our circumstances! Sorry! Usually ships within 2-3 days! Thank you!
