The KOSH set nested together: burnt jackfruit wood with three concentric hand-hammered brass rims
Overview

Tree rings, in brass.

KOSH is a series of handcrafted coasters that blend traditional Indian craft with a modern aesthetic.

Each piece works as an everyday utility item and as a canvas of cultural expression. The form comes from the organic patterns of tree trunks, and it's made with Thathera, a heritage metal craft from Punjab.

Research & ideation

Inspiration & craft

KOSH pairs the organic resilience of tree rings with Thathera, a UNESCO-recognised craft. Artisans in Punjab hammer the brass by hand, and a burnt finish mimics the texture of aged wood.

The design moves a heritage technique into a contemporary form that stands for rootedness and life.
