Cast-iron tea kettle (tetsubin 鉄瓶)) crafted using the traditional lost-wax process, a meticulous method that allows for fine detail and elegance in metalwork. The body is adorned with a delicate pine needle motif and the lid's finial is a small pine cone, symbolizing longevity and resilience.

Tetsubin artisans inherit their craft through familial lineages, and several have been honored with the prestigious designation of Living National Treasure, reflecting the cultural and artistic significance of this enduring Japanese tradition.
