How does the Flipstraw lid prevent spills and make drinking effortless?

• Flip-up straw for quick sips without tilting the tumbler.
• Snap-shut mechanism that reduces accidental openings.
• Proper assembly and tight closure required for leakproof performance.
• Not intended for carbonated or hot beverages — use cold only.

Double-wall vacuum insulation keeps cold beverages chilled for hours by minimizing heat transfer from the outside environment. The 40 oz size holds ample liquid for long outings, reducing the need to refill frequently.

• Double-wall vacuum construction for extended cold retention.
• 18/8 recycled stainless steel resists odor and flavor transfer.
• Wide capacity suits long commutes, workouts, and day trips.

How should I clean and care for this tumbler to maintain performance?

This tumbler is dishwasher-safe for standard home dishwashers but hand washing preserves finish and artwork longer. Avoid commercial-strength dishwashing or high-heat cycles and never use cleaners with high chlorine or bleach levels to prevent vacuum or finish damage.

• Dishwasher-safe for normal household use; hand washing recommended for aesthetics.
• Use mild detergent and warm water for hand washing; soak with baking soda for stains.
• Remove lid during long soaks to prevent pressure buildup.
• Do not freeze, microwave, or use with hot or carbonated drinks.
