Meet the Tumbler 270ml Voronoi, a stainless steel vessel inspired by the raw textures of nature. Its distinctive surface pattern recalls rugged cliff faces and the geometric beauty of plant cell nuclei. Artisans individually hand-apply a matte finish to the molded ridges, creating a tactile surface that feels wonderful to hold. With a standard 270ml capacity, it is lightweight and easy to carry whenever you need a quick sip or a moment to pause.
