It presents an all-over uniform fine granular rough matte finish, covered with evenly distributed tiny raised particulate grains that create soft, subtle uneven tactile relief across the whole surface. The panel maintains consistent compact grain density without obvious directional streaks or deep grooves, showcasing a plain, minimalist solid flat facade with natural hand-finished earthy tactile texture. Vertical narrow dividing gaps separate individual slabs neatly, delivering clean segmented wall assembly effect while retaining delicate uniform granular roughness on every panel surface.
