This is a classic square model, the CASIO Baby-G BG-5601. The black and pink color scheme is cute, and it's a popular design that's easy to match with casual outfits. The battery has been replaced (December 2025) and is currently working correctly. Simple operation check (button operation, display switching, backlight illumination) has been performed, so you can use it immediately upon arrival. Although there are some light scratches and minor marks due to it being a used item, the display is clear and there are no problems with use. Please check the photos for the detailed condition. Only those who understand that this is a used item, please. *Only if there is a malfunction upon arrival (e.g., not working), please contact us before leaving feedback and we will respond.
