Stanley Quencher H2.0 Flowstate Tumbler - Black

Yes, all components of the tumbler are dishwasher safe for easy and convenient cleaning.

This specific tumbler has a capacity of 0.89 liters.

Absolutely. The double-wall vacuum insulation is designed to keep both hot drinks hot and cold drinks cold for extended periods.

It is constructed from durable 90% recycled 18/8 stainless steel, ensuring longevity and an eco-friendly profile.

The innovative FlowState lid rotates to three positions: a straw opening (straw not included), a drink opening for direct sipping, and a fully closed top for enhanced leak resistance when not in use.

The FlowState lid offers enhanced leak resistance when in the fully closed position. However, like most tumblers, it is not 100% leak-proof if inverted, especially when using the straw or drink opening.

For best results, pre-heat your tumbler with hot water for hot drinks or pre-chill with ice water for cold drinks for a few minutes before adding your beverage. Always ensure the lid is securely closed.

18/8 stainless steel refers to a grade of stainless steel containing 18% chromium and 8% nickel. This composition makes it highly resistant to corrosion and rust, durable, and food-safe, without imparting metallic tastes to your beverages.

Ensure the lid is securely closed in one of the three FlowState positions. Check for any damage or dents to the tumbler's exterior, as this can compromise the vacuum insulation. Make sure the tumbler was pre-heated with hot water or pre-chilled with cold water before adding your beverage for optimal performance.

Verify that the rotating FlowState lid is properly aligned and seated on the tumbler. Ensure the silicone gasket within the lid is correctly positioned and free from debris. When using the straw opening, remember it is not fully leak-proof if tipped. Use the fully closed position for maximum spill resistance during transport.

Thoroughly clean all parts of the tumbler and lid, including disassembling the rotating FlowState lid if possible, using warm soapy water. Allow all components to air dry completely before reassembling or storing. Periodically clean with a solution of baking soda and water to neutralize odors, followed by a thorough rinse.
