Please understand that there are some minor scratches as this is not a new item. It's in quite good condition as I polished it when listing it. 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 (¥21,000) 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, so I will include them. Since I bought them together, I have one box, which I can also send. Please rest assured that these were purchased new from a Hirotaka retailer.
