In fact, I personally recommend several ways to identify the Millennium boat board. Generally, there are grade marks on the Millennium boat board, such as EO or E1. You can have a look. Then knock down the wood-faced solid wood material with your hands, and it will make a crisp sound, while the sound of wood-based panels is relatively low. Then look at the security label on the board, and finally look at the fineness of the layout.
