Thermos thermal mug THERMOS REFRESHING SERIES black matte 850 ml, vacuum-insulated drinking bottle

Thermos REFRESHING SERIES thermal mug in black matte finish with 850 ml capacity is a vacuum-insulated drinking bottle designed to keep beverages hot or cold for extended periods while minimizing external condensation. The compact cylindrical shape and screw lid create a spill-resistant container suitable for commuting, office use, travel and outdoor activities. The matte surface provides a non-reflective look and a comfortable grip, while the stainless interior preserves taste and is straightforward to clean.

Advantages

The vacuum insulation reduces heat transfer to maintain beverage temperature and limits sweating on the outer surface. The 850 ml capacity accommodates larger servings, reducing the need for frequent refills. A screw-on lid with secure closure improves leak resistance during transport. The internal stainless-steel lining resists odors and stains and supports hygienic cleaning. The compact form and matte finish combine practicality with a subtle, durable appearance.

Suitable for

• Carrying hot coffee or tea for commuting and work
• Keeping cold drinks chilled during outdoor activities or exercise
• Traveling by car, train or plane where spill resistance is needed
• Use in offices, workshops or on-site jobs that require a large-capacity mug

How to use

Pre-rinse the thermal mug with warm water before first use. Fill the mug with a hot or cold beverage and secure the screw lid by turning until it is tightly closed. For best temperature retention, preheat or precool the mug by filling it with hot or cold water for a few minutes and then emptying before adding the beverage. Open the lid to drink and close immediately after to reduce heat loss. Wash the interior regularly with warm soapy water; the lid can be cleaned separately to remove trapped residues.

Usage recommendations

Avoid using the thermal mug in microwave ovens. Do not place it directly on open flames or stovetops. When carrying hot liquids, ensure the lid is fully secured and transport the bottle upright. For prolonged freshness of beverages, clean the mug after each use and allow all components to dry completely before assembly and storage.
