It doesn't work. The condition is as shown in the photos. Also, as this is a used item, we kindly ask that those who are extremely concerned about the condition or are very sensitive to such matters refrain from purchasing. Furthermore, I do not smoke, nor do I have any pets. We ask for your understanding and only accept purchases from those who agree with these conditions. Immediate purchase is welcome. ⚠️ Caution Negotiations for price reductions are not accepted. (We will not respond to requests for price reductions, so please be aware of this.)
