Thank you for viewing. This is a giriko (powder for archery) container made from processed walnuts. To put giriko in, remove the Phillips screws with a small Phillips screwdriver. The container is designed to split in half, so please put the giriko in while it is open. *When closing the lid, align the walnut halves properly and tighten with a Phillips screwdriver. If they are misaligned, the giriko may leak. This is highly recommended for those looking for stylish archery equipment. It will be shipped via Mercari便, wrapped in packing material, protected from moisture, and placed in a dedicated box. We take care to pack each item carefully from the buyer's perspective. We are very grateful to our repeat customers and those who continue to follow us, so we include a small bonus gift. Please let us know in the comments. New customers are also very welcome. Thank you for your consideration.
