I own two of these "de Buyer" Mineral B Pro pans, 24 cm and 32cm, purchased at different times on-line, from CookCulture.
I am very pleased with not only the performance of these pans but dealing with this company. Jed's videos pertaining to seasoning, post seasoning and cleaning of carbon steel pans are very informative and his seasoning paste works very well indeed. I would highly recommend acquiring this paste and also their Fine Chainmail scrubber.
CookCulture and Jed are excellent to deal ...
