The vacuum insulation keeps fluids scalding hot for hours. Always pour your beverage safely into the included screw-top cap cup before consuming to avoid severe tongue or mouth burns. 1. Initial Washing: Wash all pieces thoroughly with warm soapy water before using the flask for the first time. 2. Pre-Conditioning Loop: To achieve maximum thermal retention, fill the flask with boiling water (for hot drinks) or ice water (for cold drinks) for roughly 3-5 minutes, then empty it completely before adding your beverage. 3. Filling Clearances: Pour your beverage inside, leaving at least 2 cm (0.78 inches) of space below the bottom edge of the stopper to prevent overflow when sealing. 4. Stopper Sealing: Thread the push-button valve stopper assembly smoothly into the flask opening. Twist clockwise until it is entirely flush and locked down tight to guarantee full leak-proof performance. 5. Serving Liquid: Press the integrated stopper button to open the pouring valve, tilt gently to pour your beverage into the external cap cup, and press the button again to seal it shut between uses. ✔ Fabric Care & Washing Instructions Dishwasher Safety Profile: While the main water bottle body components are technically labeled dishwasher safe, our professional team strongly recommends hand washing our vacuum sealed containers. Hand Wash Guidelines: Hand wash using a soft bristle bottle brush, warm water, and mild dish soap. Avoid using abrasive steel wool pads or harsh chlorine bleach sanitizers that can degrade the premium 304 stainless steel surface. Leave the cap off to air dry completely. ✔ Package Content Inventory List 🍾 1 x Unbranded Stainless Steel Vacuum Thermal Flask Bottle (In Selected Capacity Size) 🥛 1 x Multi-Functional Screw-On Cap / Insulated Drinking Cup ✔ Important Buyer Instructions & Terms Manual Measurement Deviations: Due to factory automated manufacturing lines and manual measurement methods, please allow a minor physical layout tolerance variance margin of 0.5 cm (0.20 inches).
