The higher cost of wood slabs can be attributed to a few factors. Firstly, it takes considerable time and effort to find and select premium slabs from mature trees. Additionally, the process of carefully drying and treating the slabs to ensure their durability and quality is labor-intensive. Finally, the unique and appealing characteristics of wood slabs, such as their natural edges and captivating grain patterns, contribute to their increased demand and subsequently higher prices in the market.
