This is a tsuba (hand guard) to be attached to a Kendo shinai (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. Due to the manufacturing process and storage, there are some scuffs on the back (plain side), but this does not affect its use. The front side (patterned side) is in relatively clean condition. ■Regarding the All Japan Kendo Federation Rules "Tsuba (hand guards) shall be circular, made of leather or synthetic materials. Their size shall be within 9 cm in diameter and they shall be fixed to the shinai." Immediate purchase is welcome / Feel free to ask any questions.
