Silicon flashing, aluminum base, processed to 200mm outer diameter

This is for the chimney of a log house currently under construction. It was temporarily processed to 200mm and placed on the roof, but it has been replaced with a different flashing, so I am listing it for sale.
Since it was temporarily placed on the roof, there are signs of use on the sheet part.
Pickup is also possible in Oyacho, Yabu City or Himeji City.
