This is a set including a large quantity of seal materials, along with the necessary tenkoku knives, carving knives, and high-quality vermilion ink. There are approximately 60 seal materials. Most are already carved, but they can be re-carved. The tenkoku knives are not cheap ones, but proper quality tools. The vermilion ink is also a high-grade product. This would be suitable for those who are just starting to carve, or for calligraphers. The seal materials alone are valuable. Please consider this only if you understand that the items are already carved.
