This wok has thickened cast iron walls and edges, which can better store heat and effectively control oil fume. The thickened bottom of the pot is not easy to stick to the pot even if the fire is full, and at the same time, the cooking nutrition is firmly sealed in the pot. The middle and lower parts add more flavor. The handle is fixed with walnut wood and 304 stainless steel screw, which is durable and high in quality.
