Travel thermos mug Maestro MR-1643-30A 0.3 L, stainless steel, green, vacuum insulated, leakproof

Maestro MR-1643-30A is a 0.3 L travel thermos mug designed for everyday mobility. Constructed from double-wall stainless steel with vacuum insulation and a cool-touch rubber housing, this green travel mug keeps hot drinks warm for up to 12 hours and cold drinks chilled for up to 24 hours. The lightweight 245 g design, non-slip base and overflow protection make it suitable for commuting, short trips and office use. The lid features an odour-proof, leakproof cap with an open-close button and a spout for convenient one-handed drinking.

Advantages

The vacuum-insulated double-wall construction minimizes heat exchange to maintain beverage temperature while the cool outer housing prevents the mug from becoming too hot to hold. A leakproof, odour-proof cap with an open-close button and spout reduces spills and prevents unwanted smells. Overflow protection and a non-slip base increase stability during use, and the lightweight stainless steel and plastic build balances durability with portability.

How to use

Before first use, wash the thermos mug with warm soapy water and rinse thoroughly. Open the cap using the open-close button, pour in your hot or cold beverage and securely close the lid until it clicks to ensure the leakproof seal. Drink from the integrated spout; operate the button to open and close the pouring channel. Allow the mug to cool before disassembling for cleaning parts that are removable according to the manufacturer’s instructions.

Usage recommendations

To maintain insulation performance and hygiene, preheat or precool the thermos by pouring a small amount of hot or cold water inside, letting it sit briefly, then emptying before adding your drink. Hand wash the cap and body components as instructed; avoid using abrasive cleaners or placing the product in the dishwasher if the manufacturer advises against it. Close the cap tightly during transport and avoid overfilling to ensure proper overflow protection.
