Was looking at the Lodge offering at the local Wallmart when I saw this IMUSA cast iron wok. Picked it up and couldn't believe how thin and light it is. Almost as light as steel. It has got to be malleable cast iron as it is so thin I think regular grey iron would break too easily. Seems to be ground inside. Just amazed at how thin and light it is. It is 14" in diameter.
I don't want one, but it is interesting to handle.
