Thank you for viewing. These items are handmade by an amateur as a hobby, so please purchase them if you understand the nature of handmade goods. There may be marks or distortions from using pliers. 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 if you would like me to do so. Overall length: 13cm (height) x 16cm (width) x 2.7cm (thickness) Clock: 9cm diameter
