Legendary model! GA400 series! Looks like it's made of LEGO blocks! The most pop-style G-SHOCK! ❗️Battery is dead!❗️ ❗️It may work after a battery replacement, but I cannot guarantee it!❗️ Please understand this before purchasing! Purchased new at a certain mass retailer a few 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. 5398, which is engraved on the back cover! A very beautiful item with no aging deterioration! The item (with tag) will be shipped by 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 ships within 2-3 days! Thank you!
