This is a palm-sized Go (囲碁) book. I think it's easy to read even when traveling. I've included a photo at the end with a ballpoint pen for size comparison. The ballpoint pen is not included. It's new, unused, and in beautiful condition. Please take a look at the photos and consider purchasing if you understand that it has been stored at home. I have one more of the same item. ◉ I will take measures to prevent water damage when shipping. ◉ I can also accommodate combined purchases with other items. ◉ If there are any areas you are concerned about, I will add more photos with close-ups. ◉ Please feel free to comment if you have any other questions. Thank you for looking.
