Kuksa

A kuksa, as it is called in Finnish, is called guksi in Northern Sámi and kåsa in Swedish.
It is a traditional drinking mug, made from carved birch burl. As an extra is the little piece of reindeer antler in/on the handler.
Son P. gave it to me as a gift from Finland, as a souvenir.
I didn't drink coffee from it yet, I first have to prepare it (some procedure to follow, but it is all in finnish/suomi).
