SM22E is one of the popular products we are producing for the buyers world wide. It is made of cast iron, and it is very firm and strong. This model has a perfect size that you don't have to worry about if it's too big or too heavy to carry it! The diameter of it is 22.5cm, and the height is only 4.8cm as the largest model is 6.7cm. Other than the size, it is also good for both indoor and outdoor cookings. The reason why we only make cast iron cook wares is that cast iron can make the fire spreads all over the pot, and the food would never stick to the pot.
