Product information

Description

Thermos flask Maestro MR-1638-75 0.75 L Graphite is a vacuum-insulated bottle designed to maintain beverage temperature for extended periods. With a 0.75 litre capacity and a graphite finish, this flask is compact enough for daily commuting, travel and outdoor activities. Its construction reduces heat transfer and supports spill-resistant transport of hot tea, coffee or cold drinks while fitting most bags and car cup holders.

Advantages

The flask uses vacuum insulation to minimise heat exchange, helping to keep liquids hot or cold for hours. A compact cylindrical design and corrosion-resistant interior make cleaning and maintenance straightforward. The screw-top lid provides a secure seal to reduce leaks during transport, and the neutral graphite colour offers a discreet, unbranded appearance suitable for a variety of settings.

Suitable for

  • Daily commute and office use
  • Travel and long drives
  • Hiking, camping and outdoor recreation
  • School or university
  • Everyday home use and picnics

Key specifications

  • Capacity: 0.75 L
  • Insulation type: Vacuum insulated
  • Finish: Graphite colour
  • Material: Double-wall construction with corrosion-resistant interior
  • Closure: Screw-top lid with spill-resistant seal
  • Shape: Compact cylindrical design suitable for most cup holders

How to use

Before first use, wash the flask with warm soapy water and rinse thoroughly. Preheat or precool the flask by filling it with hot or cold water for a few minutes, then empty and pour in your desired beverage. Secure the screw-top lid tightly to maintain insulation and minimise spills. After use, disassemble the lid if possible and clean all parts; allow to dry completely before reassembling and storing.

Usage recommendations

Do not place the flask in a microwave or freezer. Avoid using bleach or abrasive cleaners on the interior finish. For best thermal performance, avoid frequently opening the lid and preheat or precool the flask when transporting temperature-sensitive drinks.
