Carved from a solid piece of duralumin, these sake cups have a thickness of just 0.6mm. ⬜️
Duralumin is a strong, hard, lightweight alloy of aluminium, widely used in aircraft construction. The intricate pattern, known as "kiriko”, is designed to reduce the surface area that your fingers come into contact with, keeping the cold sake from getting too warm. 🥃
