Thank you for viewing! OMRON MC-510 ear thermometer This is a long-term storage item, but it is unused. It comes with 10 probe covers. Operation confirmed (I used a probe from my home) I inserted a battery purchased from Daiso to confirm functionality. In accordance with Mercari's rules, only images of the main unit are posted. There is no box. If you would like the instruction manual, I will include it, but its condition is not very good (it has yellowing, etc.).
