Both were purchased here about 3 or 4 years ago. The Toyo University book has notes in colored pen from the time of purchase, and there are many more besides the images on pages 3-6. The Tokyo Keizai University book has no writing. There are scratches on the surface, but they are not very noticeable. This is a set of two books. I want to sell them, so I've set the price quite low. Instant purchase is OK ⭕️
