Wrist band designed by Kazuma Iwata of Iwata Mokko, the makers of the Mugen kendama.
Kazuma was aiming at a way to prevent sweat from dripping down onto his kendama hand when playing the kendama for extended periods or in hot weather. The wrist band is a terricloth style stretchable towel-like material in navy or black with an image of a kendama and the Japanese characters for "Mugen" embroidered on it.
