Thank you very much for viewing the product. This is a tsuba (handguard) for a bokuto (wooden sword). When I was learning kenjutsu (sword techniques) before, I thought it would be nice to have a tsuba for a bokuto with a unique design, so I made this using a 3D printer. If you purchase this, please select one of the following designs: goldfish, deer, or carp, and let me know in the comments. ● Material 　Matte PLA (black) ● Thickness 　Approximately 3.8mm ● Size 　Approximately 78mm ● Notes 　① I was able to attach it to the bokuto I use. 　　However, there may be variations in the thickness of the bokuto, so you may need to 　　sand the inside of the tsuba. 　② Tsuba stoppers are not included. Please use commercially available tsuba stoppers to 　　secure and use the tsuba. 　③ For Hira-mine bokuto only. Thank you for your understanding.
