I bought this skillet new from Amazon with inner surface machined.  
I had to sand it inside out with fine 110 grid sand paper to get rid of the burrs left by machinning on inner surface, and outside surface with edges to smooth out so my hand could touch all over...
I have too many cast iron cookwares in my garage.  I need to let this one go.
Overall, good quality cast iron pan after I detailed it inside out.
From smoke and pet free family. 
Ship to continental USA only.
Happy bidding.
