Hallmark Keepsake Star Trek Romulan Bird-of-Prey Ornament 2011 Ship Christmas This ornament takes those little button batteries that are LR41. These were collectors pieces so the batteries were removed so they didn't corrode. Taped to the top side of the ornament I took it off to test it and the batteries will need to be replaced but I will leave them so that you can order more.
