This is a T-fal wok pan. Ingenio Neo, for gas stoves only, not compatible with IH (induction heating). Vintage Bordeaux Intense Size: Inner diameter 28cm I purchased this as a single item two years ago. It's a slightly larger wok pan than those included in the standard set. I've used it on a gas stove for two years, so it shows signs of use, but until recently, food didn't stick or burn even without oil. Please understand that this is a used item before purchasing. I also have a 28cm frying pan that tends to stick without oil, but I was using it alongside the wok pan until recently. It's not in the best condition, but I'll include it as a free service if you'd like.
