Go Study: January 2013 - December 2013, 12-book set, with supplementary booklets! This is a specialized magazine where you can learn the depths of Go. There are some signs of reading, but there are no problems with viewing. There may be occasional writing. I will erase any that I notice before sending. The supplementary booklets are mini-sized and easy to carry. The content includes problem sets and answer explanations, so you can think and work through them, making it a great learning tool. If you would like multiple years, I will discount 300 yen for each additional year. (Example: 300 yen off for purchasing 2 years, 600 yen off for purchasing 3 years) Please let me know in the comment section before purchasing. I hope someone can make good use of these ☆彡
