It has been stored for a long time at my parents' home. Please understand. I do not have specialized knowledge, so I cannot provide details. I apologize (´；ω；`). There are several places with stains. Please check the photos. When shipping, I will send it in simple packaging. As this is amateur inspection and home storage, if you are even slightly concerned, I apologize, but please refrain from purchasing (><). We ask for purchases from those who understand.
