Our beautiful dark brown wood frames are made from FSC certified solid linden wood that has been treated with a colored finish. Handmade by craftsmen in Europe, the frames come with real, flat 2mm-Floatglas for all sizes up to and including 50cm x 70cm. In size 70cm x 100cm, the frame comes with a 2mm anti-reflective Plexi-glass. As it is still a natural material, variations in colour and texture may occur compared to the product images shown. Note that prolonged exposure to direct sunlight can cause wood color to fade over time.
