It keeps the nutrients and superb food taste.
Perma-Life 9 star is ingeniously designed with tightly joined lid and container. Because of this, it makes a water sealing affect that keeps the nutrients and food tasty during cooking. The product is used with a small amount of water and oil to reduce the loss of nutrients (Vitamins /Minerals), therefore, allows us to cook and taste the food as it is.
What is water sealing affect?
It is an effect that blocks the tiny steam running in and out of the container to make a low-moisture, low-oil cooking. Also, it stops the slippery lid from overflowing when boiling a food.

There is a special vapor valve whistle.
Vapor Valve Whistle is a special attachment on the lid that notifies the level of heat to avoid food burnt or overflow. Since the lid blocks the evaporation, it prevents the nutrients of the food getting oxidized or ruined.

Saves time and energy
Since 9 layered container has great heat conductivity and maintenance of surface temperature, a food can be cooked in a half-heat in short time

Elegant and functional design
The handle is made with a strong and heat-proof stainless material. You don’t have to worry about a cleaning burnt plastic handle anymore.

When you get a new product, there is a possibility of detecting a small bit of oil and chemical left from a manufacturing process. Clean before use to prevent the food from sticking on surface or discoloration.

How to clean before use?
