I love mystery parcels that just turn up out of the blue. Especially when they contain Catan sets I do not have.
This 2015 Seafarers set is from Brazil and uses local Portuguese. While the game is by Devir, it also features the Kosmos logo on the rear. Both Devir (Spanish/Portuguese language sets) and 999 Games (Dutch language sets) have often had the Kosmos logo on so I presume they are subcontracted to print the sets.
