Cast iron has superior heat retention for even cooking, restaurant quality searing and comes pre-seasoned for teflon like non-stick cooking surface when used with a thin layer of oil. It’s also ridiculously strong and rugged. 
Use with confidence on all cooking surfaces: gas, electric, induction, oven, broiler, grill and even the camp, a campfire, or the fire pit. 
Your wok can rust so keep it out of the dishwasher, do not soak and dry immediately after cleaning. Use warm water, scrape any stuck bits with a spoon, a little elbow grease with a rag and finish with a paper towel. Lightly polish with a stainless steel chainmail scrubber for a smooth patina. 
Proudly designed in the USA, pre-seasoned with our proprietary oil blend, cast from the finest virgin ore and built to last for generations to come.
