Go Study: January 2018 - December 2018, 12-book set, with supplementary booklets This is a specialized magazine where you can learn the depth of Go. There are some signs of having been read, but there are no problems with viewing. There may be occasional writing, but I will erase anything I notice before sending. The supplementary booklets are mini-sized and easy to carry. They contain problem sets with answers and explanations, so you can think and work through them, which is great for learning. 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
