M661 series presents a richly layered and visually engaging surface, composed of a dense arrangement of stone-like fragments embedded within a uniform base. The pattern features an intricate mosaic of irregular chips that vary in size, shape, and distribution, creating a natural yet carefully balanced visual rhythm. The interplay between the fragments and the base introduces a refined diversity in texture. These fragments appear scattered in a seemingly random configuration, but the overall effect is harmonious, giving the surface a cohesive, well-structured appearance reminiscent of traditional terrazzo.
