Over 10 years ago, I wanted to decorate my room in an Asian style, so I used this as interior decor. I bought this myself during a trip to Thailand. It requires one AA battery to operate. The size is approximately 14.5cm wide x 11.5cm high x 3.5cm deep. This item has been in someone's possession before. Please refrain from purchasing if you have any concerns or are looking for a perfect item.
