1. The solid wood part is 100% pure solid wood, no veneer, no artificial board. 2. The main material is poplar. After long-term carbonization at medium and low temperatures, poplar can better retain the original performance strength of the wood, greatly reduce the chance of cracking, improve stability, and at the same time increase antibacterial, insect-proof and anti-corrosion properties for durability. 3. The auxiliary material is New Zealand pine, which is used for box baffles, cross partitions and floor boards. It has good toughness, stable properties, light texture, straight grain and few knots. 4. The auxiliary material is paulownia wood, which is used for the bottom plate of the box. It is corrosion-resistant, wear-resistant, high-temperature resistant, non-deformable, and not easy to mold. It has been the material for making bellows pull rods since ancient times and is also a famous piano-making wood in ancient China.
