Purchased used four years ago. Used about once or twice a week. After practice, I wipe off sweat with a towel and use Resesh (odor eliminator). I also hand wash it with detergent about once every six months. [Important Notes] ・There are areas that do not conduct electricity due to rust and fraying, so they have been repaired with conductive tape. ・There are also several tears on the inside. ・The coating on the back of the mesh part peeled off after being washed with water several times, making it feel a bit brighter when worn. ・The tongue is slightly torn, so it has been repaired with tape. ・The name tag area will be blacked out before shipping. Please use it for practice. Please understand that it is non-refundable and non-returnable.
