The Cook-Pal Ren is a super unique line developed by Yoshikawa Co. and manufactured in Niigata, Japan. This is probably the first Wok that is made of iron, doesn't come with any sort of thin coating like Teflon yet it won't really stick. The special high-temperature treatment technique developed by Yoshikawa actually penetrates into the surface of the steel, therefore they won't peel off like Teflon coationg. This is particularly important when cooked with high-heat.
We have successfully developed supreme rust-resistant and anti-caking steel woks and frying pans.
