Is this wok nonstick? I bought was what I thought was a carbon steel wok, but after realizing that it's black color means it isn't a "classic" carbon steel wok, I am trying to find out what it is made out of :)

I am pretty sure that it is this product, which says it is a black oxide coating: https://www.alibaba.com/product-detail/Fry-Pan-Chinese-Wok_254864972.html

Does this just mean it is preseasoned or is it possible this is Teflon/Xylan or something like that?  Anyway to tell if it has a coating or not?
I have a similar wok, I bought at Target. It was described as "seasoned". I thought I was buying a genuinely seasoned wok. 

Nope. It was a black coating just like the one you linked to. 

It's a non-stick coating. It worked well for a few meals, then it started to peel.

I used a plastic scrubby to clean the sauce that stuck to the pan, and it cut through the coating. From now on, I will not buy anything from Target. Lie to me one, and you are done.

I paid $80 for it a few years ago. $80 would buy a genuinely seasoned wok back then.
