TOCA UDU CERAMIC DRUM This is a model with a head that you hit in the center. It is not a current product. It is thought to be a rare model now. In normal use, hitting the head produces a high-pitched sound. It makes a different sound from the "pechi-pachi" sound of hitting the body, and interesting patterns can be created by combining the hits. I used it for a while, but then stopped using it. I stored it in its original box in a non-smoking room, but many stains appeared naturally. It's not that it got wet or was stored in a humid place. I wiped it, but it wouldn't come off. Please refer to the photos. There is no problem with playing or the sound. It will be sent in its original box.
