The Birchbark Collection is the original collection which brings traditional Finnish birch bark into contemporary eyewear design. The frame fronts feature natural birch bark, while the temples are crafted from reindeer antler. Each piece of birch bark is unique, with shades ranging from golden yellow to deep brown, even within a single tree. The collection is primarily made to order at Keloa’s atelier in Sodankylä, Finnish Lapland.
