This desktop duo pairs a square-section metal pen cup with a circular bamboo-base holder featuring a laser-cut lattice pattern. The geometric forms create a balanced visual contrast, while the openwork design of the cylindrical piece allows quick identification of contents. The solid metal construction offers stability, complemented by the natural texture of the smooth bamboo platform beneath the lattice cup. Suitable for organizing writing tools in contemporary home offices or professional workspaces, this coordinated set focuses on clean silhouettes and functional material harmony.
