Grain
Grain is a finely textured cork design in wheat, honey and soft natural brown, with small fragments gathered closely together like grain scattered across warm sand.
It feels even, gentle and quietly tactile. The subtle variation creates depth, while the consistent colouring keeps the overall surface calm and easy.
Crafted by Granorte. Curated by Natrul.
