Glass Bottle with Temperature(310ml)

It features a built-in tea infuser or strainer, typically made of stainless steel, for steeping tea leaves directly within the bottle. 

The double-wall insulation helps to maintain the temperature of your beverage, keeping it hot or cold for extended periods. 

Some models incorporate a magnetic controller to manage the tea infuser's position for optimal brewing. 

These bottles are often made from high borosilicate glass, known for its heat resistance and durability. 

They are a convenient and eco-friendly alternative to single-use tea bags or disposable cups.
