A very rare K. Yairi novelty item I received at a musical instrument fair a long time ago. This is a set of 3 types, 5 pieces in total, not for sale. Although it has been stored, there are some scratches, etc., from when I received it as a novelty item, so please refer to the photos. The colors differ depending on the material. The larger ones are made from waste material from when the sound holes were made. You can tell it's a high-quality top material with a very fine grain.
