This durable beverage container maintains hot and cold temperatures throughout the day using a specialized six-stage heat retention process. Designed exclusively for adults, the flask is fabricated from SUS304 grade stainless steel, which guarantees a non-toxic, odorless interior that safely holds coffee, milk, fruit juice, or herbal infusions without altering taste.
Available in six distinct finishes including matte black, polished gold, standard blue, classic silver, gradient blue, and gradient red, the vessel caters to varied personal styles. Three capacity configurations ensure the correct volume for every routine. The 500ml option measures 21.5 x 6.8cm, the 800ml size reaches 23.5 x 8cm, and the full-liter model extends to 28 x 8cm.
Touching the built-in digital panel instantly illuminates the current fluid temperature, effectively eliminating guesswork and preventing accidental scalds. A reinforced bottom ring absorbs impact during drops, while the food-grade silicone gasket locks securely beneath the metal cap to guarantee zero leakage during transport.
Sipping directly from the wide mouth provides a smooth, unobstructed flow rate. For carrying convenience, each unit features a robust nylon loop strap that easily secures around hands or attaches to external gear. This versatile thermos delivers reliable performance for workplace hydration, fitness center visits, weekend camping excursions, and everyday travel needs.
