Bunny has no 22 cm pine board. Of course not. Ousong is the trademark of Beixin Wood Industry, and Dehua Bunny can't use it. It's called the core board, just like the European pine board made in Germany. If you are talking about oriented particleboard, then Bunny has it, which is the core board. However, the core board can not be laminated directly, and can only be pasted with high-density board. It may also be LSB, and it is not known whether LSB is imported or not.
