SIGG - Thermo Flask Gemstone ONE Vacuum Thermal flask (0.5L)

The SIGG Gemstone IBT Obsidian water bottle is the ideal companion for all leisure activities, school or the office. The simple black look is an elegant finishing touch to the convenient and functional design. Its first-class double-walled insulation makes this bottle ideal for carrying various drinks, which it will keep warm for up to 18 hours and cold for up to 25 hours. The practical screw cap is guaranteed leak-proof.

Thanks to the high-quality 18/8 stainless steel construction, the bottle is robust. To ensure a long usage life, wash by hand. The super-thin inner construction of the flask means it is smaller and lighter than other thermos bottles. All materials used to make the food-safe bottle are BPA-free and do not contain pollutants like phthalates or oestrogenic substances.

Gemstone Thermo Flasks

Made from double-layered stainless steel, the Gemstone Series flasks keep tea and coffee consistently warm. The modern thermo flasks in Obsidian or Selenite designs are not only as robust and stylish as stainless steel, their material and double-layer vacuum-insulation construction allow them to keep every drink hot or cold for hours.
