Stanley Quencher H2.0 Flowstate Tumbler - 890 ml - Green

The Stanley Quencher H2.0 FlowState Tumbler in this variant has a capacity of 890 ml.

It keeps drinks cold for up to 9 hours and iced for up to 40 hours due to its double-wall vacuum insulation.

Yes, the tumbler and its lid are top-rack dishwasher safe for easy cleaning.

The FlowState™ lid is a versatile lid with three positions: an opening for the reusable straw, a full-open position for drinking directly, and a fully closed position to prevent spills.

It is constructed from recycled 18/8 stainless steel and is BPA-free.

Yes, it includes a reusable straw that fits securely within the FlowState™ lid.

The tumbler features a narrow base designed to fit most standard vehicle cup holders.

Ensure the lid is securely closed and the straw is properly inserted. For best results, pre-condition the tumbler by filling it with hot water for hot drinks or cold water for cold drinks for a few minutes before use. Ensure the double-wall vacuum seal is intact.

Check for any obstructions around the lid seal or the rotating part of the FlowState mechanism. Rinse the lid under warm water and try again. Ensure the tumbler is not overfilled.

Clean the straw thoroughly with a straw brush. Ensure no ice or fruit pieces are lodged inside. Check that the lid's straw opening is clear.

This indicates a potential issue with the vacuum insulation. Contact customer support if the problem persists after ensuring the lid is sealed correctly.
