Hiromi Sato created Sora COCORO (宙 COCORO, meaning "Sky Heart" or "Cosmos Heart") using maki-e, a technique of sprinkling metallic powder onto wet lacquer to create decorative designs. Using astronomy references, Sato hand-places each constellation and celestial body with sharpened toothpicks, applying lacquer and gold powder to a stainless steel base.

The lacquer is fired in a specialized baking process, creating water-resistant, durable pieces. When filled with liquid, the cups reveal shimmering, galaxy-like patterns that evoke the vastness of the cosmos.

• Hand wash only with neutral detergent and a soft sponge or cloth. Avoid abrasive scrubbers, scouring pads, cleansers, and cleaning powders, which can scratch the surface. Dry thoroughly before storing to prevent white mineral deposits from forming.
• Not microwave safe. Do not use on direct heat such as in an oven or on a gas stove.
• Do not use chlorine-based or oxygen-based bleach.
• Stainless steel is resistant to rust, but avoid storing in contact with other metals (such as iron or aluminum) or in humid environments, as this may lead to corrosion.
• The colors are coat by baking, making the decoration highly durable and water-resistant. However, the oxide coating may be scratched if rubbed with sharp or hard objects.
