This is a handmade wrist strengthening bar. I have made this for wrist strengthening training. Length: Approximately 340mm Weight: Approximately 530g Thickness: Approximately 16mm The handle is firmly wrapped with a non-slip braided cord. Due to its weight, it strengthens the wrist. * For wrist training in Kendo, Iaido, etc.! * It is safe to possess if you do not carry it outdoors! I have confirmed this by inquiring with public related organizations! * There may be scratches from the manufacturing process. * Although made with new materials, some minor scratches from the manufacturing process can be seen, so I am listing it as "slightly scratched or dirty." * Because it is handmade, please refrain from purchasing if you are concerned about minor imperfections!
