Designed in a rugged Stanley-type profile and manufactured using premium stainless steel, this vacuum tumbler delivers reliable hot and cold insulation for extended hours, making it suitable for work, travel, fitness, and outdoor activities.

Built with double-wall vacuum insulation technology, the tumbler is designed to keep beverages hot for up to 12 hours and cold for up to 24 hours.

Why Choose a Stainless Steel Vacuum Tumbler

A stainless steel vacuum tumbler is an essential everyday accessory for maintaining beverage temperature and preventing spills. Unlike single-wall containers, vacuum-insulated tumblers create a thermal barrier that significantly reduces heat transfer. This technology ensures beverages remain at their intended temperature for hours, regardless of external conditions.

The 1200ml Redberry Stainless Steel Vacuum Tumbler combines thermal efficiency with structural durability. Its stainless steel body does not retain odors or flavors, ensuring each drink tastes fresh. The robust construction also makes it a sustainable alternative to disposable cups and low-quality plastic bottles, supporting long-term use and reduced waste.

Leak-Proof Performance of the Stainless Steel Vacuum Tumbler

One of the defining features of this stainless steel vacuum tumbler is its FlowState leak-proof lid. Engineered to prevent accidental spills, the lid provides a secure seal during movement, making the tumbler suitable for backpacks, gym bags, and car cup holders. This leak-resistant design is particularly beneficial for commuters, travelers, and active users who need dependable spill protection.

The lid also allows smooth and controlled drinking, reducing splashing and improving overall usability. Whether you are walking, driving, or exercising, the 1200ml Redberry Stainless Steel Vacuum Tumbler ensures your beverage stays contained and accessible.

1200ml Redberry Stainless Steel Vacuum Tumbler for Daily Hydration

Designed for extended daily use, this vacuum tumbler offers a generous 1200ml capacity that supports consistent hydration throughout the day. This is especially advantageous for individuals with demanding schedules, long workouts, or outdoor activities where access to refills may be limited.

The wide-mouth opening enhances convenience by allowing easy filling, cleaning, and the addition of ice cubes. This practical design feature reduces maintenance effort while improving versatility. The 1200ml Redberry Stainless Steel Vacuum Tumbler is suitable for both hot and cold beverages, making it a year-round hydration solution.

The Stanley-type exterior of this stainless steel vacuum tumbler delivers a rugged yet modern aesthetic that appeals to both professional and casual users. Its ergonomic shape provides a comfortable grip, while the balanced structure ensures stability when placed on flat surfaces or in standard car cup holders.
