Oshiri Tantei Volume 11 Bundle Sale

I've checked all the volumes, and the pages themselves are sturdy. Since I've only read them a few times, there are no torn pages at all. The spines are also in good condition without any cracks. The quality is better than I expected, which is why it's priced this way. However, the corners of the books are slightly bent, so please refrain from purchasing if this is a concern for you.
Immediate purchase OK!
Individual sales from Volume 5 onwards OK, priced at ¥440 per volume.
If you purchase all 11 volumes, you'll save ¥8,000 compared to the original price of around ¥10,000, and I'll include a bonus gift, so it's highly recommended.
Price negotiation OK!
