This is the best non-stick marble wok. Made of premium quality aluminium and Marble coated with 5 layers of Non-Stick Coating, top with Granite outside, this wok is absolutely remarkable. Nothing will ever stick to it. Most of the time, all you need is a paper towel to wipe off any residue before you can reuse again. Unlike other non-stick cookware coated, this ceramic coating is safe and 10x stronger than Teflon coating. It will withstand temperature up to 800 degrees Fahrenheit and yet have the heat distributed evenly to avoid burn spots. PTFE and PFOA free, this wok is not only good for you but is also environmentally safe. Perfect Gift for Christmas, Mothers' Day, Fathers' Day, Weddings, Hose Warming, Birthdays and just about any occasion.
