Ken Hom Performance stainless steel, non-stick premium woks deliver outstanding performance and durability as well as being stylish, practical and ease to use. Performance stainless steel woks feature an encapsulated alloy core which improves hear transfer for improved cooking performance. The woks are coated with a non-stick HALO coating designed to distribute the heat more evenly and quickly (62% faster than standard non-stick coatings), which means the food cooks faster and more evenly and eliminates “hot spots” that burn food. This coating is also metal tool suitable and dishwasher safe. This wok comes with a 5 year guarantee.
