Tumbler 360ml Voronoi Regular price: ¥16,500 This surface processing is inspired by the rock faces of cliffs honed by harsh natural environments and the geometric patterns of cell nuclei of diverse plants that inhabit the surrounding areas. The unevenness created by a unique molding method is then given a matte finish by craftsmen, one by one. The 360ml size, which is a longer version of the 270ml, is the perfect size for a standard cafe or convenience store's medium-sized coffee, making it useful for use in the office or for staying hydrated when you're out and about. The "Basic line" is a series with a minimalist design that makes the most of the original texture of stainless steel. TSUTSU has been polished, drawing on the history and rich nature of Tsubame-Sanjo as a source of creation.
