This is a supporter to be worn under kendo kote (protective gloves). It helps to reduce the pain when struck. It contains Sorbo cushioning, and I used to love it because it hurt less than sponge ones. Cushioning material is included not only for the wrist but also for the base of the thumb. Size M I used it from late elementary school to the first year of junior high school. There are traces of a name sticker having been peeled off. It has considerable signs of use, with fraying and small holes, but it is still perfectly usable. I washed it with sports detergent every time after use, so there is no odor. For those looking for a replacement or those who find sponge supporters too painful and want to try something else. Please understand the condition described above. Kote (Protective Gloves)
