Those seeking a robust, taste-neutral drinking experience without plastic leaching concerns will find this a superior choice. If you require a completely leak-proof seal for vigorous activity or carrying hot liquids upside down, consider a screw-top lid model. ## How to use 1. Fill the tumbler with your desired hot or cold beverage. For best results with hot liquids, pre-heat the tumbler with hot water for a few minutes before filling. For cold liquids, pre-chill with ice water. — Prepare Your Drink 2. Place the slide lock lid onto the tumbler, ensuring it is properly seated. Slide the lock mechanism to the open position if you intend to use a straw (for cold liquids only) or to drink directly. — Secure the Lid 3. Slide the lock to the closed position when not drinking to minimize spills. While the lid offers spill resistance, avoid carrying hot liquids upside down. The Griptec base provides stability on flat surfaces. — Use and Transport 4. After use, clean the tumbler body and lid. The tumbler is top-rack dishwasher safe. Hand washing with warm, soapy water is recommended for longevity. Ensure all parts are thoroughly dried before storage. — Cleaning and Maintenance ## Product details | Field | Value | |---|---| | Primary Material | 18/8 Stainless Steel | | Lid Material | BPA-Free Plastic (assumed, not specified) | | Insulation Type | Vacuum Double-Wall | | Recommended Uses | Home, Travel, Office, Car | | Suitable for | Hot or Cold Liquids | | Temperature Retention (Approximate) | Hot: Several Hours, Cold: Many Hours (Specific hours not stated by manufacturer) | | Cost per use | 18 oz (532 ml) tumbler — ₹3,902 per tumbler | | Shelf life after opening | N/A (Durable Product) | | Contraindications | Not fully leak-proof when lid is open or for carrying hot liquids upside down.
