Thank you for looking. This is a giriko (powder for sharpening) case made from beautifully processed ebony-like wood. It is a very hard wood with a beautiful grain. This is a stylish, slim giriko case with an excellent feel. The more you use wood, the more character it develops and the more attached you become to it. Highly recommended for those looking for stylish archery equipment. It will be shipped via Mercari便, wrapped in packing material, then bubble wrap, and finally placed in a waterproof bag. We take care to pack each item carefully, considering the buyer's perspective. Thank you very much. Sports... Kyudo (Japanese archery)
