Thank you for looking. This is a handmade item made by an amateur as a hobby, so please only purchase if you understand handmade items. There may be marks from pliers and some distortion. The clock is battery-operated. It requires one AA battery, which you will need to provide. I can also include a battery for an additional 50 yen, so please let me know in the comments section. Height 16cm x Width 19cm x Depth 3cm Clock diameter 9cm
