“Reiwa 06-nen Image & Clever Method: Kayanoki Sensei's Basic Information Technology Engineer Classroom” by Atsushi Kayanoki Price: ¥1680 I bought this to improve my skills and have read it through once. I was careful not to write in it, so there are no markings. I checked it for this listing and didn't see any, but I apologize if I missed something. There are no particular stains, but please understand that this is a used item before purchasing. Also, the thickness is exactly 3cm, which is the absolute limit for sending via Nekopos (a Japanese delivery service), so I'm afraid I'll have to put it directly into a bag. I've priced it accordingly to reflect this! #AtsushiKayanoki #Atsushi_Kayanoki #Book #Electrical & Mechanical/Electronic Communication
