These are stone materials for Tenkoku (seal carving) collected by my late father when he ran a calligraphy school. The stone materials themselves are unused, but the original boxes have yellowing and fraying due to aging, so please refrain from purchasing if you are sensitive to such issues. These are three sets of Tenkoku stone materials, each with a lion statue carved on them. - Each set contains two stones.
