This is a delicious frying pan made by Fujita Metal, as seen on DAIGO's Kitchen in Mikke. It has a hard temper finish. I've used it twice, but I'm not used to iron frying pans, so I'm selling it because I haven't been using it. The oil seasoning is already done, so you can use it right away. To clean it, just wash it with a scrubbing brush, and it's compatible with all heat sources. This is a used item, so please refrain from purchasing if you are sensitive to this. I bought a scrubbing brush for cleaning, and I have one extra, so I'll include it as a bonus.
