Downsizing due to collection reorganization. This is a strategy guide for the Famicom game Super Black Onyx. The contents have some signs of use, such as yellowing and fading due to aging, but there are no missing pages, loose pages, or writing, and there is no problem reading it. However, please understand that there may be oversights. I think it's in relatively good condition for a used book from nearly 40 years ago, but this is my personal opinion, so please check the photos carefully before considering a purchase. There are no smokers in my family, but I do have a small dog. However, I also purchased this item used. To prevent swapping, cancellations and returns after shipping are not accepted for any reason. Please understand this is a used item and consider purchasing only after carefully checking the condition in the photos. Due to the nature of my job, which involves frequent business trips, it may take 2-3 days to ship depending on the timing. I will gradually lower the price if it doesn't sell, so please refrain from price negotiations. You can purchase without a comment, but please forgive me if it's sold out as I am also selling it elsewhere. Please read the profile before purchasing.
