“I have a 3-month-old and I used to just use my hand to gauge how hot the water is. Sometimes I’m really afraid I would get it wrong and cause injuries to my girl. This thermal flask has been a life-saver, I know exactly how hot the water is by pressing on the touch screen. Must have for mommas!”

Using scalding hot water to prepare milk for babies is dangerous and could potentially cause burns to baby’s mouth and lips. When an agitated and hungry baby is crying, it could be unsafe to arbitrarily gauge the water temperature with touch. The little one could reject the cold milk or cry uncontrollably if scalded by the overly hot milk, causing guilt and remorse.

The innovative TesFlask™ features advanced technology that enables real-time water temperature sensing with a simple tap. TesFlask™ provides immediate feedback on the water temperature with a digital display along with vacuum insulationEnjoy the satisfaction of having perfectly prepared warm milk that will provide nourishment and joy for the little one.




LED SMART DISPLAY: With a simple tap, the LED display shows the current water temperature. This ensures users know exactly how hot the water is.

VACUUM INSULATION:  With a copper-plated lock layer, the TesFlask™ maintains heat effectively. Have specific water temperature for milk formulas without the wait.

LEAK-PROOF: The TesFlask™ lid is reinforced with an air-tight silicone lining. This provides a secure fit at the neck of the bottle to prevent leakage.

BUILT-IN STRAINER: A strainer is built into the top of the TesFlask™ which allows users to steep a perfect cup of tea and drink it at the desired temperature.



We understand how frustrating it can be when babies are hungry and fussing, and you don't know how hot the water is. It can be upsetting and distressing when little ones reject overly hot milk or get burnt by it.  Studies show that over 18% of paediatric burn cases were attributed to excessively hot water used to prepare milk formulas.

With the TesFlask™, take the guesswork out of having the perfect water temperature for milk formulas. The TesFlask™ innovative tech enables real-time water temperature sensing and displays it with one simple tap. Enjoy the ease of always being able to provide perfectly warm milk, so little ones are kept happy and contented!
