Although unused, this item is several decades old. I tested it by inserting batteries, and it works. The approximate size is: 17 cm wide at the base and 22 cm high. Please allow for some error. It also had a pendulum, but I didn't attach it for fear of damage. As this is an old item, those seeking perfect condition or performance should purchase a new, modern product. I cannot accept returns or complaints, so please only purchase if you understand the nature of vintage items. The outer box is not part of the product. One battery is included, but it's from the original time and is unusable. I'm including it for nostalgia's sake, as some may appreciate it. I'm currently clearing out my parents' house. I will need to go to my parents' house to ship the item, so I may not be able to ship it immediately. I visit weekly, so I will ship within a minimum of 7 days. If you are concerned about shipping, please ask questions beforehand. Thank you.
