Superior Construction and Performance Features

Premium Materials for Unmatched Durability

The foundation of any exceptional tumbler lies in its construction materials. Our Classic 20oz Stainless Steel Tumbler Bulk collection utilizes food-grade 304 stainless steel, renowned for its resistance to corrosion, staining, and rust. This premium material ensures your beverages remain pure and uncontaminated while providing exceptional durability for daily use. The robust construction withstands drops, impacts, and daily wear, making these tumblers ideal for both office environments and outdoor adventures. Each tumbler weighs a comfortable 263g with dimensions of 8.8×17.2cm, providing the perfect balance between capacity and portability. The 304 stainless steel construction also contributes to the tumbler's recycling potential, aligning with our eco-friendly manufacturing philosophy and reducing environmental impact compared to single-use plastic alternatives.

Advanced Temperature Retention Technology

Experience remarkable temperature preservation with our upgraded insulation technology. The Classic 20oz Stainless Steel Tumbler Bulk line maintains hot beverages at optimal drinking temperature for up to three hours and keeps cold drinks perfectly chilled for an impressive nine hours. This exceptional performance comes from our double-wall vacuum insulation design, creating an effective thermal barrier that prevents heat transfer. Unlike inferior insulated containers, our Stainless Steel Tumblers remain comfortable to hold regardless of the temperature of the contents inside. The exterior never develops condensation with cold beverages, eliminating the annoying "sweat" that can damage surfaces or create slipping hazards. Each tumbler includes a specially designed splash-proof lid with a convenient sipping hole, allowing for comfortable drinking while minimizing the risk of spills during commutes or in busy office environments.

Innovative Leak-Resistant Design

Nothing ruins a day faster than discovering your favorite beverage has leaked throughout your bag or vehicle. Our Classic 20oz Stainless Steel Tumbler Bulk collection features an innovative leak-resistant design that gives you confidence on the go. The precision-engineered lid creates a secure seal with the tumbler body, preventing liquid from escaping even when the container is tipped or jostled. The drinking spout includes a sliding cover mechanism that can be securely closed when not in use, providing additional protection against accidental spills. This thoughtful design element makes our Stainless Steel Tumblers ideal companions for commuting professionals, active lifestyles, and travel scenarios. Additionally, the ergonomic shape fits standard cup holders in vehicles and exercise equipment, while the non-slip base prevents tipping on flat surfaces. These practical design features combine to create a truly user-friendly drinking experience that adapts to your active lifestyle without compromising performance.

Customization Options for Brand Enhancement

Versatile Logo Application Techniques

Elevate your brand identity with our diverse logo application techniques for Stainless Steel Tumblers. Our Classic 20oz Stainless Steel Tumbler Bulk offerings can be personalized using multiple high-quality methods, each delivering distinct aesthetic and tactile characteristics.

For those seeking distinction, our specialty finishes include eye-catching glitter infusions, luminous glow-in-the-dark coatings, and ice flower textures that create a crystalline appearance. Each finish is carefully applied in our state-of-the-art facility using environmentally responsible processes that minimize waste and emissions.
