It works. Purchased on Mercari this April. I'm not a nurse, but I bought it because I thought it was cute to have at the office. The second hand ticking is quite loud, so it was kept in a drawer. I took it out of the bag once, but it has been sleeping in a drawer at the office in the condition shown in the photos. ・Instant purchase welcome! 　・No smokers, no pets 　・I am not responsible for postal delays. 　　Please be patient. 　・If you are looking for perfection, please go to a store and buy a new one. 　・Returns after the item arrives are troublesome, so please relist it on your end.
