〇 "A Book to Understand Practical NLP Techniques" Keishi Yamazaki Price: ¥1800 〇 "You Can Get Rid of Your Weaknesses" This is a set of two books. As shown in the photos, there is some soiling on the top of the books. The gray area on top is not a stain. The light brown areas are stains. Due to this, there are a few stains of about 1 to 2 square centimeters on the top of the pages inside. Personally, I don't mind it at all, but please be sure to inquire if you are concerned. There is no problem at all with reading them. Also, if you are not overly sensitive, I don't think you will mind. It's a great deal as a set of two books, so thank you for your understanding.
