We're extra proud of our own series of picture frames that we call Blocky. This series is made specially for truly large picture frame sizes. The picture frames are manufactured in Sweden and have acid-free backboards, as well as extra powerful 2 mm acrylic (as compared to other frames that only have 1 or 1.5 mm). This makes for a strong picture frame that really lasts and does justice to your biggest and most beautiful pictures.
