The double-wall structure has low thermal conductivity, preventing hot or cod from transferring directly to the hand, ensuring a comfortable grip even with hot or cold beverages. Four cups stack precisely inside the body without shaking, and its excellent corrosion resistance and durability allow for easy and hygienic maintenance.
