A traditional kuksa cup made of a Finnish eco composite material - way better than a regular plastic cup, still virtually impervious to elements. You can do anything with this except burn it or put it in the microwave. Tea spoon included. The Kupilka 21 is one damn fine cup that not only looks nice, but has a long service life and is virtually care-free (just wash it now and then of course). It also gets a beautiful patina in use! The word Kupilka comes from Karelia and means 'favourite cup'.
