Ravensburger puzzles are designed to be a positive experience. Following with tradition, our puzzle dies are completely hand made from the grid design to the bending and forming of our steel tools; creating a perfect interlocking fit with no tearing or dust. No two pieces are ever the same shape! Extra-thick cardboard pieces mean your puzzle will last for years and our fine, linen-structured paper eliminates glare so you can really see the details. Ravensburger, bringing families together since 1891.
