The Dino puzzle collection consists of 12 to 6,000 pieces, allowing children to engage creatively in their free time. It is ideal for kids as it helps with hand-eye coordination, shape recognition, and their motor skills. The puzzles improve the observational and memory skills of both children and adults, while the difficulty level can be increased depending on the total number of pieces that make up the puzzle. They are made from high-quality thick paper that does not fray at the edges, and once completed, you can even frame them! The number of pieces is mentioned in the title description of each puzzle. The Dino collection puzzles are made in the Czech Republic using quality materials.
