Ravensburger 500-40,000 piece Puzzles are a fun way to keep you sharp by strengthening your logical thinking and short term memory while having fun! Since 1891 we've been making the world's finest puzzles in Ravensburg, Germany. Our attention to detail has made Ravensburger the world's greatest puzzle brand! We use an exclusively developed, extra-thick cardboard combined with our fine, linen-structured paper to create a glare-free puzzle image for a quality you can see and 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. Enjoy Ravensburger quality with this family-friendly activity today!
