glass cup 450ml Magnetic Cup, Magnetic Tea Brewing Cup, Tea Water Separation Cup, High Temperature Resistant High-peng Silicon Portable Advertising Gift Cup

•Dual Temperature Control: Equipped with double-wall vacuum insulation, insulated bottles maintain hot liquids (e.g., coffee, tea) at 50–60°C (122–140°F) for 6–12 hours and cold drinks (e.g., ，smoothies) at 4–10°C (39–50°F) for 12–24 hours, preventing condensation on the exterior.

•Safe Materials: Typically made from food-grade 304/316 stainless steel or BPA-free plastic, ensuring no metallic taste or chemical leaching. Lightweight designs with non-slip grips and leak-proof lids (e.g., screw-top or flip-lid) make them ideal for commuting, workouts, or outdoor activities.

•Versatile Design: Many models feature a wide mouth for easy ice cube insertion and cleaning, while some lids double as drinking cups. Additional features may include built-in thermometers, carry handles, or compatibility with car cup holders

•Temperature Limits: Avoid filling with boiling water (>100°C/212°F) to protect the lid’s silicone seal and prevent scalding. For cold use, pre-chill the bottle with ice water for 5 minutes before adding drinks.

•Cleaning: Hand wash with mild soap and warm water; use a bottle brush for the interior and a small brush for lid grooves. To remove odors or stains, rinse with a mixture of baking soda and water or dilute vinegar, then air-dry completely. Never use bleach or abrasive cleaners, as they may damage the coating.

•Leak Prevention: Always check that the lid is tightly sealed before carrying. Overfilling past the “max” line may compromise the seal, leading to spills.

•Storage: Store empty bottles with the lid open in a dry, cool place to prevent mold growth. Avoid prolonged exposure to direct sunlight or high temperatures, which can degrade plastic components.

•Safety Note: For children, choose models with sippy lids and supervise use to prevent burns from hot liquids. Replace damaged seals or cracks immediately to maintain insulation efficiency.
