This set includes four wooden, 12-piece construction vehicle jigsaw puzzles—a cement mixer, a bulldozer, a dump truck, and an excavator. Each is stored in a separate compartment of a sturdy wooden box! The slide-on box lid doubles as a convenient puzzle board! Each puzzle piece is shape-coded on the back for easy sorting. They’re great for travel! Playing with puzzles is a great way for kids to develop problem-solving skills. This Melissa & Doug Construction Vehicles 4-in-1 Wooden Jigsaw Puzzles set is an exceptional gift for kids ages 3 and up. Add the Melissa & Doug Rainforest Floor Puzzle to round out the puzzle play experience and to give kids an engaging option for screen-free fun.
