Purchased approximately 4 years ago for 27,000 yen on Amazon Marketplace (receipt image attached). I originally bought a tenkeyless model, but then decided I wanted a tenkeyed one. I accidentally bought another tenkeyless model and had it in storage for a while. After opening the box, I stored it in a case with a calculator, and there is a faint 5cm scratch on the back (see the last photo). As mentioned, this item was purchased by mistake, so it has never been used for typing.
