The Berlinger Haus Vacuum Flask – 0.75L in Matt Black is a sleek, compact solution for keeping beverages hot or cold while on the go. Designed with both style and performance in mind, this flask features a high-quality 18/10 stainless steel inner body and a durable matt powder-coated exterior in an elegant black and silver color scheme.

Equipped with advanced double-wall vacuum insulation, the flask maintains your drink's temperature for extended periods — keeping liquids hot for up to 8 hours and cold for up to 12 hours. The 0.75-liter capacity is ideal for personal use, whether for hot coffee during a commute or chilled water during outdoor activities.

Its comfortable grip, easy-to-clean design, and premium construction make it both functional and fashionable. Packaged in a half gift box, it also makes an excellent gift item.

Cleaning Instructions:

1. Before First Use:

   • Rinse the interior of the flask with warm soapy water.

   • Rinse thoroughly and allow it to air dry with the lid removed.

2. After Each Use:

   • Wash by hand with warm water and mild detergent.

   • Use a bottle brush to clean inside thoroughly, especially after storing coffee, tea, or flavored beverages.

   • Rinse well and air dry with the lid off.

3. Deep Cleaning (for Stains or Odors):

   • Fill with a mixture of hot water and 1 tablespoon of baking soda or white vinegar.

   • Let it sit for a few hours, scrub gently if needed, then rinse thoroughly.

4. Exterior Cleaning:

   • Wipe the powder-coated exterior with a soft damp cloth.

   • Avoid abrasive sponges or harsh cleaning agents to preserve the matte finish.

Care Instructions:

• Do not place in dishwasher – hand wash only to maintain insulation and finish quality.

• Not suitable for microwave or freezer use.

• To improve thermal performance, pre-heat or pre-chill the flask with hot or cold water for a few minutes before use.

• Avoid filling with carbonated drinks or dairy products for extended periods to prevent pressure buildup or spoilage.

• Store open when not in use to avoid moisture or odor buildup.
