This is an alarm clock from FM NACK5. The design resembles a donut record, and it's very cute! Size: 13 x 13 x 5 cm Runs on 3 AA batteries. The alarm sound is the NACK5 jingle. It sounds like "〜efuemunakkufaivu♪〜". I have confirmed that it works, but since it's at least 20 years old, the time accuracy is not clear. I would like to sell it to someone who understands this. Thank you very much. #HalloweenOnMercari
