Customers are Finnish puzzle enthusiasts and gift-buying consumers served almost exclusively in Finland and Åland, with limited Sweden-bound shipping subject to surcharge. Kolmiokirja Oy is wholly owned by Keesing Media Group B.V., a Dutch conglomerate described as Europe's largest crossword/puzzle magazine publisher, and the website and data practices operate under KMG's online network.
