Leather Tsuba 'Migaki' is handmade using genuine leather. Each piece varies in color and texture, resulting in individual differences. As it is made from natural leather, it may have natural features such as leather grains, blood vessel marks, and stains. We appreciate your understanding of these characteristics. Using mink oil for leather care will enhance its texture remarkably. The more you use it, the more unique character and appeal the leather tsuba will develop. These are meant to fit standard shikumi shinai and not meant for thick grip shikumi shinai.
