Stanley Quencher H2.0 Flowstate Tumbler - Rose Quartz 2.0

The FlowState lid is designed with three positions, including a full-cover top to prevent splashes and minimize leaks. However, like most tumblers with a straw opening, it may not be 100% leak-proof if fully inverted.

Yes, the Stanley Quencher H2.0 is expertly engineered with double-wall vacuum insulation to maintain the temperature of both hot and cold drinks for hours.

This particular model, the Stanley Quencher H2.0 Flowstate Tumbler - Rose Quartz 2.0, has a capacity of 0.89 liters.

The tumbler and its lid are dishwasher safe, making cleaning convenient. For hand washing, use warm, soapy water and ensure all components, especially the lid's gasket, are thoroughly cleaned and dried.

It is constructed from durable, high-quality 90% recycled 18/8 stainless steel.

The Stanley Quencher H2.0 is designed with a tapered base to be compatible with most standard car cup holders. (Info needed: confirm base diameter for specific car models).

The FlowState lid refers to Stanley's innovative rotating lid that offers three functional positions: a dedicated straw opening, a wide mouth opening for drinking, and a full-cover top to prevent splashes and spills.

Ensure the FlowState lid is securely fastened and rotated to the closed position if not actively drinking. Check for any visible damage to the tumbler's body, which could compromise the vacuum insulation.

Verify that the silicone gasket on the lid is properly seated and free from debris. Confirm the FlowState lid is rotated to the full-cover top position. While designed to prevent splashes, tumblers with straw openings may not be 100% leak-proof when fully inverted.

Disassemble the lid by carefully removing the rotating part and silicone gasket for thorough cleaning. Use a small brush (like a straw brush) to clean crevices. The tumbler is dishwasher safe, which often provides a more thorough clean.

Ensure the tumbler has been thoroughly washed before first use. If the taste persists, try cleaning with a mixture of baking soda and warm water, letting it sit for an hour before rinsing. If the issue continues, contact Stanley customer support.
