Hokkaido Ukulele Workshop Quian Original castanets. It seems that the materials are made using natural Hokkaido wood. These are cute castanets that give you a sense of the warmth of wood. The owls are also cute, so how about using them as interior decoration? *We do not sell them individually, so we sell them as a set. *I've been displaying them cutely since I bought them. *Please consider purchasing them with the understanding that they are used items. *Please refrain from purchasing if you are nervous, to prevent any trouble.
