Middle School Boys' Shinai (Bamboo Sword) - Size 37, Koga (Tiger Fang) Genuine Octagonal, 26mm, SSP, For Practical Use Set of 3, 2 are unused. Treated with bamboo sword oil for approximately 3 months. May feel a little heavy at first, but the oil will permeate the entire sword and it will become more manageable. Afterwards, it will be less prone to splintering and will last a very long time. No longer needed due to changing grade levels. I hope a swordsman with large hands will use them. Thank you.
