• Premium Material Construction
The flask is constructed from 304 stainless steel, a high-grade material known for its durability and resistance to rust and corrosion. This ensures that the inner wall of the flask remains intact and hygienic, making it safe for storing beverages. The use of food-grade virgin plastic for the lid and silicone for the seals enhances safety, ensuring that no harmful chemicals leach into your drinks. This attention to material quality is a key factor in maintaining the purity and flavor of your beverages, be it hot coffee, tea, or cold water.

•  Insulation Technology
One of the standout features of the 480ml flask is its vacuum insulation technology. This dual-wall vacuum construction provides good thermal retention, keeping drinks hot or cold for extended periods. Whether you need to enjoy a hot drink on a chilly morning or want to keep your water cool during a summer hike, this flask delivers outstanding performance. Users can expect their beverages to remain hot for up to 12 hours and cold for up to 24 hours, making it a versatile companion for all occasions.

The flask's design focuses on user convenience. The 480ml capacity is nice for daily use, offering enough volume to keep you hydrated without being overly bulky. Its bullet shape makes it easy to grip and carry, whether you’re commuting, exercising, or traveling. The wide mouth opening allows for easy filling, pouring, and cleaning, which is particularly beneficial when dealing with ice cubes or larger beverage containers.

• Leak-Proof and Spill-Resistant

This leak-proof design is nice for tossing in your bag without the fear of spills, making it an ideal choice for those on the go.
