These are the "Kin MUGEN" kote (wrist protectors). The palm is made of durable brown micro-punch material. The shape is designed to be held mainly with the pinky, ring, and middle fingers, making it easy to grip and giving a feeling of being able to put power into the tip of the sword when striking. There are no tears in the palm, and I think it's in pretty good condition. It's durable yet lightweight, and the palm is also strong, so I think it's a kote that can be used for a long time.
