The 100-piece format is perfect for school-age kids and older but the wagon full of puppies that’s pictured when they come together will melt hearts of all ages. Five golden retriever puppies fill the red metal wagon, big paws overhanging the side and adorable faces snuggled close together. What an adorable incentive to solve the puzzle. Melissa & Doug cardboard jigsaw puzzles are made using durable, high-quality materials and handmade dies that make every piece shape unique. The sturdy pieces resist peeling, fading, and creasing, so the stunning high-gloss artwork will stay looking great for years to come.
