(See 2nd image)
There was a sticker on the back that I peeled off, but it's still a bit sticky.
There are some markings on the surface that I tried to erase, but a little bit remains.
Please consider these points before purchasing.
Reference Price:
The price on Amazon is ￥21,000, so this is a very good deal.
