Since 1891 we've been making the finest puzzles in Ravensburg, Germany. It's our attention to detail which makes Ravens burger the world's greatest puzzle brand. We use an exclusively developed, extra-thick cardboard and combine this with our fine, linen-structured paper to create a glare-free puzzle image for a quality you can feel. Our steel cutting tools are designed and crafted by hand. This ensures that no two pieces are alike and guarantees a perfect interlocking fit.
