This is a tsuba (hand guard) with a leather tsuba-like design that is attached to a shinai (bamboo sword) for size 39. This product is made with a 3D printer using plastic (PLA) as the material. PLA is lightweight and easy to handle, making it a suitable material for daily practice. When using it in a match, we recommend attaching it so that the plain back side is visible. ■Size ・Inner diameter: approx. 34mm ・Outer diameter: approx. 81mm ・Compatible with: Shinai size 39 ■Condition This is a new, unused item.

Their size shall not exceed 9 cm in diameter and shall be fixed to the shinai." Immediate purchase is welcome / Feel free to ask any questions.
