I have kept this unused in my closet at home for a long time. I am selling it because I have no opportunity to use it. As far as I can see, there are no discoloration or stains. I think there is some deterioration over time, so I would appreciate it if you could purchase it with your understanding. ↓ Amateur measurements with a measuring tape.
