Thank you for viewing. This is an item I'm selling that I'm not using. It's a Shaviv set. The items are a bit old, but they are in good condition. It comes with two B 20 spare parts. I'm not sure if this will be helpful, but I looked it up online and found the approximate prices: C40: ¥13,000 C42: ¥22,000 D80: ¥13,000 B10~B30: ¥1,600~¥2,500 B600: ¥5,500 B70: ¥10,000 The case has scratches, but there are no cracks. Please check the photos before purchasing. Thank you!
