4. Setup
First Use Preparation:
- Unpack: Carefully remove all components from the packaging.
- Wash: Before initial use, wash the tumbler body, lid, and straw thoroughly with warm, soapy water. Rinse completely.
- Inspect: Ensure all parts are clean and free from any debris.

Using the FlowState Lid:
The FlowState lid features a rotating cover with three distinct positions:
- Straw Opening: Designed to securely hold the reusable straw in place and resist splashes.
- Drink Opening: For direct sipping without the straw.
- Full-Cover Top: Provides a sealed closure for transport, though it is not entirely leak-proof when tipped.
Filling and Drinking:
- Fill: Remove the lid and fill the tumbler with your desired cold beverage. Do not overfill.
- Secure Lid: Place the FlowState lid firmly onto the tumbler, ensuring a snug fit.
- Select Position: Rotate the lid cover to your preferred drinking position (straw, drink opening, or closed).
- Insert Straw (if applicable): If using the straw opening, insert the reusable straw.

6. Maintenance and Care
Cleaning Instructions:
- Hand Wash Only: To preserve the finish and insulation properties, hand wash all components with warm, soapy water.
- Avoid Abrasives: Do not use abrasive cleaners or scrubbers, as these can damage the tumbler's surface.
- Drying: Allow all parts to air dry completely before reassembly or storage.
Storage:
Store the tumbler with the lid removed to allow for air circulation and prevent odors.
7. Troubleshooting
Common Issues:
- Leakage: The FlowState lid is designed to resist splashes but is not fully leak-proof if the tumbler is tipped over. Ensure the lid is securely fastened and the cover is in the full-cover position for best splash resistance.
- Reduced Temperature Retention: Ensure the lid is properly sealed. Pre-chilling the tumbler with cold water before adding your beverage can enhance cold retention.
