Model RD-1300TS1 is designed and produced by Rang Dong, Vietnam’s leading manufacturer of vacuum flask products.

Similar to other Rang Dong's thermos products, the tea flask has a glass inner with silver plating and vacuum technology, forming 5 layers of insulation to ensure it keeps the liquid in storage hot for 12 hours, and cold for 24 hours. A vacuum insulation layer is designed to ensure the heat won't leak and also to prevent water vapor from condensing.

The glass quality is equivalent to laboratory and medical glass, with a high level of chemical resistance and thermal stability. It is accredited as meeting technical requirements for food safety, sanitation and hygiene. The glass does not affect the taste of the herbal tea and can keep it fresh for extended hours.

Moreover, the flask body is decorated with colorful patterns and can be customized as per customer's requirements. This product is also made to be user-friendly thanks to the sturdy PP plastic body and the silicone gasket ensuring the leak-free and heat retention performances.  

In addition, the non-slip base of the product can be easily opened to replace the glass refill in case of breakage.



This herbal tea flask can be used to prepare the user's favorite herbal tea, which is beneficial. A cold winter day won't go by without having a hot cup of tea, which can help us avoid catching colds and flu. Such a hot cup will surely boost our immune system.

A hot herbal tea can be served with a snap, using Rang Dong's herbal tea flask.

The mouth of the flask is optimally designed with a 80-mm diameter, which gives way to easy refill of water and also makes it convenient to clean up. The well-balanced handle and the 1.3-liter capacity make the flask portable and can be used in various locations. 

The elegant design of the thermos also contributes to the cozy atmosphere embracing the gathering. 

The tea flask can be used anywhere thanks to its compact design.

One important note when using the product is that users should avoid filling it up over the lid, otherwise pressing the push lever would create pressure that induces splashing.
