It has a powerful grain pattern and a lustrous beauty. It has been used since ancient times as the main pillar of houses, as well as for the construction materials of palaces and shrines, and for high-quality furniture. Burl Rare because it can only be obtained from limited parts of the tree, such as the trunk and roots. The causes of burl formation include damage to the tree from insects, injuries, diseases, typhoons, etc., which cause abnormal cell proliferation during the repair process, as well as genetic factors. Various patterns appear, such as swirls, ripple patterns, and eye-like grains.
