The 41-piece Jobsite in a Box Set includes two exclusive 6-inch XL machines (a crane and an excavator), ten 3-inch Little Machines vehicles, and 29 construction accessories for on-the-go worksite play. The articulated XL vehicles feature working booms, buckets, and hooks, allowing kids to dig, lift, and haul boulders without the need for batteries. Road signs, cones, barrels, and barricades help create realistic construction zones on carpets, sandboxes, or kinetic-sand bins to encourage imaginative play. Made from durable, high-quality plastics, the set withstands indoor and outdoor use, while its compact size fits easily in diaper bags or travel packs. The pieces support STEM learning by promoting fine-motor skills, spatial reasoning, and cooperative play for children ages 3 and up.
