This dump truck is a four part puzzle and stacking toy that rewards your child with a working truck. This stem educational toy truck encourages early childhood development of problem solving, creative play, and fine-motor skills in kids aged 3+. The fit of the parts is designed with a little wiggle room so there's no frustration as your child's motor skills are developing. The colors are molded in, not painted on. Parts are interchangeable with other Luke's Toy Factory toy trucks. Made in USA - Sustainable packaging made of recycled cardboard, doubles as a storage container.
