Let’s explore its unique features to see how the flask can win users’ trust in both form and function.
Model RD-2035 S3 from the Hanoi-based Rang Dong, Vietnam’s leading manufacturer of high-quality home appliances and lighting products, is a 2-liter thermos designed for families that value both performance and aesthetics.

Structure of Rang Dong’s vintage flask, model RD-2035 S3.
The body is constructed from durable tinplate steel with an aluminum shoulder and base, while the inner lining uses premium high-grade glass to keep beverages pure and flavor-neutral.
The vintage flask is certified for food safety and hygiene, confirming that all materials in contact with water meet established health standards.
Exceptional features
What sets the model RD-2035 S3 apart from modern stainless-steel alternatives is its premium glass inner lining.
Unlike metal-lined flasks that can sometimes alter the taste of beverages, the glass interior preserves the natural flavor of tea, boiled water, or any drink stored inside, a quality that tea enthusiasts will particularly appreciate.
The tight-fitting gasket ensures excellent insulation efficiency, allowing the flask to maintain the temperature of at least 80 degree Celsius (176 degrees F) after six hours, keep drinks hot for up to 12 hours, and preserve cold beverages for up to 24 hours.
A Rang Dong’s vintage flask is placed among traditional décor, embodying the timeless spirit of a classic family ambience.
The exterior of this vintage flask is dressed in a cream-toned tinplate body adorned with a hand-painted motif of two birds perching on a bamboo stalk, an artistic style deeply rooted in Vietnamese folk culture.
This decorative design makes it not just a functional vessel, but also a nostalgic piece that complements traditional home interiors beautifully.
The generous 2-liter capacity of Rang Dong’s vintage flask makes it a reliable companion for traditional tea rituals at home.
Adding to its everyday convenience, the push-button stopper mechanism allows users to pour with one hand, reducing spills and making it especially accessible for elderly users or those managing multiple tasks at once.

Rang Dong thermos has gained its reputation in northern Vietnam decades ago, right from the 1960s when it was first produced because there was no electric or gas stove at the time, not to mention super-speed kettles, while it was cold for three to four months during winter. It may not be an exaggeration when we say the traditional thermos flask was the most essential consumer product at that time. Today Rang Dong's reputation stands firm at home and the company has also been expanding its penetration in overseas markets.
