## Long description

Maestro MR-1643-40C is a 0.4L travel thermos designed to keep beverages hot or cold during daily commute, outdoor activities or office use. The vacuum-insulated stainless body and screw-top lid provide reliable temperature retention and spill-resistant closure in a compact single-serving size. The rose finish offers a discreet aesthetic while the cylindrical shape fits most cup holders and small bags.
Advantages
The vacuum insulation reduces heat transfer to maintain beverage temperature for extended periods, while the 0.4 litre capacity balances portability and enough volume for a single serving. The screw-top lid secures the contents to limit leaks and the slim form factor makes the thermos easy to carry in a bag or place in a vehicle cup holder. The exterior finish is durable for everyday handling and the neutral design suits both casual and professional settings.
Suitable for
Keeping coffee or tea warm during commuting
Maintaining cold drinks on short outdoor trips
Use at the office for single-portion beverages
Carrying in backpacks or small handbags
When it may not be suitable
This 0.4L thermos is intended for single servings and may be too small when sharing or for longer trips that require larger volumes. It is not a replacement for insulated flasks with pour-through lids or models with integrated cups if those specific features are required. The screw-top closure requires full removal of the lid to drink directly, which may be less convenient than flip-top systems for some users.

How to use

To clean, disassemble the lid and wash with warm soapy water; rinse thoroughly and allow parts to dry before reassembly. Avoid using abrasive cleaners or strong chemicals that could damage the finish.
