Wholesale Stainless Steel Tumbler | ISO-Certified Manufacturer

Wholesale stainless steel tumblers have become a staple in the promotional products and corporate gifting industry due to their practicality, sustainability, and advertising potential. As a leading manufacturer, Zhejiang Gint Vacuum Flask Technology Co., Ltd. understands the importance of delivering products that not only meet but exceed client expectations. Our commitment to innovation is reflected in our continuous investment in research and development, particularly in vacuum insulation technology that keeps drinks at the ideal temperature for extended periods. Stainless steel is a preferred material because it is hygienic, resistant to corrosion and impact, and recyclable, aligning with the growing consumer demand for eco-friendly products. Our tumblers are manufactured dengan standard 304 food-grade steel, ensuring no metal taste or chemical leaching. The double-wall construction with a vacuum between the walls creates a barrier that prevents heat conduction and convection, resulting in ice retention for up to 24 hours and heat retention for up to 12 hours. This performance makes our tumblers ideal not only for everyday use but also for industrial applications where temperature maintenance is critical. We cater to a diverse international clientele, including distributors, e-commerce retailers, and corporate buyers. Our production capabilities include a wide range of capacities, from small 8oz tumblers for espresso to large 40oz ones for hydration. We also offer custom packaging solutions, such as individual boxes or bulk cartons, to facilitate your logistics. With a dedicated export team, we handle all documentation and comply with international regulations, ensuring smooth customs clearance. When you choose us as your wholesale stainless steel tumbler partner, you benefit from a single-source solution that combines quality, affordability, and reliability.
