Wok set includes 14-inch wok, dome lid, 12-inch bamboo spatula, and recipe bookletMade of 1-1/2 mm gauge carbon steel for fast, even heating; requires seasoning before useBirch-wood stay-cool handles - one long and an opposite helper handleNonstick steel dome lid with knob helps keep in heat, moisture, and nutrientsSafe for use on either gas or electric cooktops; hand washNOTE: Carbon steel woks are not made for average cooks that expect them to work as easily as a non-stick pan. They require seasoning when you buy it and special cleaning and oiling after every use. A properly seasoned wok will look very discolored and almost dirty, that’s what they’re supposed to look like after seasoning.
