Thermal mug LAMART LT4043 400 ml stainless steel double wall

LAMART LT4043 is a 400 ml thermal mug with a stainless steel double-wall construction that retains beverage temperature for extended periods. Designed for both hot and cold drinks, the mug combines compact portability with a spill-resistant lid and a clean, corrosion-resistant stainless steel interior. The double-wall reduces heat transfer to the exterior, improves insulation and helps prevent condensation on the outside surface, making it suitable for daily commuting, office use and travel.

Advantages

The stainless steel double-wall construction provides reliable thermal insulation while the 400 ml capacity balances portability and sufficient volume for a full cup. The smooth interior surface is easy to clean and resists flavors transfer, and the exterior stays comfortable to hold due to reduced heat conduction. The design minimizes external condensation and offers a practical opening and closing mechanism that limits accidental spills.

Suitable for

• Hot beverages such as coffee and tea for daily commute
• Cold drinks and iced beverages during travel
• Office desks and meetings where a compact thermal mug is needed
• Outdoor activities where a durable, insulated cup reduces temperature loss

How to use

Preheat or precool the mug by filling it briefly with hot or cold water and discarding before adding the beverage to improve temperature retention. Fill the mug up to the recommended level to avoid overflow, close the lid securely and carry the mug in an upright position. For best performance, avoid shaking the mug vigorously while closed to reduce pressure build-up and potential spills.

Usage recommendations

Hand wash the lid components and wash the interior with warm soapy water; stainless steel bodies are generally safe for gentle dishwasher cycles but check for any removable seals before placing parts in a dishwasher. Avoid using abrasive cleaners or steel wool on polished surfaces. Do not use in microwave ovens. Inspect seals and lid closures regularly to maintain leak resistance.
