I can't say yet if it's good or not because it's my first cast iron skillet and I've had it for a bit less than half a year, but so far I'm very happy with Maku and the price is good compared to some others I've seen on sale. Family-owned Finnish company based in Tampere, but also available here in Estonia. Don't know about their availability in other countries.

From their "Sustainability" page:

Maku products are manufactured in Europe, Finland and the Far East in factories that, if located in a high-risk country, are committed to the amfori BSCI Code of Conduct by signing the document or are audited by a third party. We use the amfori Country Risk Classification as our risk country classification.

Edit: Now looking at it apparently it is enamelled cast iron.
