Insulated Stainless Steel Tumbler | ISO-Certified OEM/ODM

The insulated stainless steel tumbler has become an essential item for consumers and businesses alike, offering a sustainable and efficient way to enjoy beverages at the perfect temperature. As a leading manufacturer, Zhejiang Gint Vacuum Flask Technology Co., Ltd. brings over a decade of expertise in vacuum flask technology, delivering products that set the benchmark for performance and reliability. Our insulated stainless steel tumblers utilize advanced double-wall insulation. The vacuum between the two steel layers virtually eliminates heat transfer, ensuring that your drink stays hot or cold for extended periods. This technology is not only practical but also energy-efficient, reducing the need for electricity-powered heating or cooling. For businesses, this means offering customers a product that supports sustainability goals while providing superior functionality. The manufacturing process at Gint is meticulous. We use premium food-grade stainless steel that resists corrosion and preserves the purity of your beverage. The manufacturing includes precise welding, vacuum extraction, and quality checks to ensure every tumbler is leak-proof and performs flawlessly. Our ISO certification reflects our commitment to consistent quality and continuous improvement. One of the key aspects our clients appreciate is customization. We understand that in the promotional products industry, differentiation is crucial. That’s why we offer a wide range of customization options: from custom colors, logos, and engraving to unique shapes and sizes. Whether you are a hotel wanting branded tumblers for guests, a corporation seeking giveaways, or a retailer looking for exclusive designs, we can bring your vision to life. Moreover, our tumblers are designed with the user in mind. The ergonomic design fits comfortably in hand and in cup holders. The leak-proof lids, often equipped with slide closures, make them perfect for on-the-go lifestyles. The easy-to-clean interior ensures no lingering flavors, and most of our tumblers are dishwasher safe, enhancing convenience. For businesses, investing in high-quality insulated stainless steel tumblers can enhance brand image. A sleek, functional tumbler with your logo becomes a daily companion for your customers, providing constant brand exposure. It is a practical item that people use repeatedly, unlike disposable cups that are quickly discarded. This longevity makes it a cost-effective marketing tool with a high return on investment.
