Please understand that there are some minor scratches as these are not new items. They are in quite good condition as I polished them when listing. Each piece is stamped with K10. The smallest one is 0.7cm (¥13,000) *Sold Out* The middle size is 1.2cm (¥17,000) The largest size is 2.0cm (¥20,000) If you wish, they can be sold separately at the above prices. We are unable to include the purchase certificate due to personal information protection. Thank you for your understanding. There are three bags, which I will include. Since I bought them together, I also have one box, which I can send as well. Please rest assured that these were purchased new from a Hirotaka retailer.
