The Ambai Tamagoyaki Iron Pan has a fiberline finish, a ultra thin coating. Fiberline is not a coating like fluorine or ceramic, but a silicone special type of coating that prevent rusting before use. The silicone coating is totally food-safe and it normally wear off after the first use. The bumpy surface reduces the contact area between the food and the pan and prevents burning and sticking. Designed by Mazoto Koizumi, Tamagoyaki comes in two diffrent sizes, small and large. The pan feature a thick bottom and an oiled finish teak wood handle.
