Construction Quality and Material Specifications

Every component of these drinking cups undergoes rigorous quality control to ensure consistent performance and user safety. From the corrosion-resistant stainless steel body to the temperature-rated sealing components, each element serves a specific functional purpose while maintaining the product's overall durability and reliability across various usage scenarios.

Stainless Steel Body Design

The 304 stainless steel construction measures 8.5cm in diameter and 15cm in height, creating a balanced profile that fits standard car cup holders while providing adequate grip surface. The double-wall vacuum insulation creates an air gap between inner and outer walls that reduces heat transfer by up to 70% compared to single-wall containers. This construction method prevents condensation on exterior surfaces while maintaining internal beverage temperatures within 5°C of original serving temperature for over three hours.
